The Summer Collection 2026 by 25 Union combines the aesthetics of cruise chic with a modern approach to knitwear – featuring a play of textures and bold silhouettes that flow with the wind. Instead of fleeting trends – openwork weaves, a calm palette, and thoughtfully designed silhouettes. Each piece, from a weightless cardigan to a flowing skirt, can be easily combined with the others and adapted to different rhythms of life – from morning coffee on the pier to an evening cocktail on the terrace.
A summer cardigan is one of the most functional wardrobe elements, a tool for creating a more expensive-looking and well-thought-out outfit. Stylists recommend:
The summer cardigan collection by 25 Union includes models of different lengths and textures: short ones – for city outfits, openwork maxi styles – for evening promenades.
The cropped Veya cardigan is a model with a precisely calculated length that does not divide the silhouette and works perfectly with high-waisted pieces. It creates a clear accent on the waist, making the legs appear visually longer. The textured ribbed knit closely follows the body, making the silhouette look more refined. The blue color emphasizes a tan and refreshes summer outfits. The Veya cardigan pairs perfectly with jeans and shorts and makes wide-leg trousers and long skirts look more balanced.
The Luma model is a stylish basic piece that softly flows over tops, linen sets, sundresses, and dresses. Thanks to its loose fit, the cardigan-coat by 25 Union:
The Luma cardigan is suitable for an evening walk, dinner on the terrace, or travel. This summer model with a soft shoulder line will be appropriate everywhere, creating the very cruise chic you came to this collection for.
Not every evening dress should be hidden under a jacket, especially if its main accent is an open back or thin straps. The Marea maxi cardigan solves this task as delicately as possible – it provides coverage without adding heaviness, softly follows the figure, creates beautiful vertical lines, and adds a noble weightlessness to the outfit.
Its practical advantages:
If Luma is about relaxed daytime chic, then Marea is about evening magic. This is women's summer clothing that creates a look with character.
The secret of the Onda openwork maxi cardigan lies in the combination of expressive texture and a simple silhouette. A solid-colour swimsuit, slip dress, or knitted set is enough to create a complete look without complicated styling techniques. The openwork knit, flared sleeves, and bohemian braided belt make the cardigan a designer tool for summer outfits inspired by cruise chic and aesthetic poolside photo shoots.
A top often becomes the starting point of a summer look. Its fit, texture, and composition determine how harmoniously skirts, trousers, shorts, and cardigans will look. In the 2026 cruise collection by 25 Union, we focused on three scenarios: a basic layer under oversized pieces, an airy tank top for walks by the sea, and an evening top with draping for cocktails on deck. The design solves specific tasks: the neckline corrects the décolletage area, the length regulates proportions, and the material ensures comfort at any time of day. Viscose adds a noble sheen and soft drape to loose-fitting summer tank tops, while cotton provides coolness and tactile comfort.
The Elyse top with thin straps is the ideal base layer under oversized cardigans, lightweight shirts, and even jackets. The textured ribbed knit makes it more interesting than a basic tank top, adding depth to the look without bright accents. The minimal top beautifully follows the silhouette without making layered outfits feel heavy. The back tie allows the fit to be adjusted to the figure while preserving clean silhouette lines. The Elyse model by 25 Union pairs harmoniously with linen trousers, maxi skirts, or denim.
The minimal Myra tank top is the basis for dozens of looks; it easily answers the questions of what to wear on a summer date or what to wear over a swimsuit at the beach. The designers made it an ideal base for intriguing and modest outfits. The model works effectively with the figure:
You can wear this loose-fitting summer tank top with linen trousers, flowing skirts, or shorts – in any combination, it will preserve a sense of cruise-inspired lightness.
Luna is a draped top that works as a designer technique. Soft vertical folds add softness and depth to the look while beautifully emphasising the décolletage line. The blend of viscose and nylon provides a noble matte glow – it shimmers in the sunset light, creating the effect of expensive fabric. The top flows beautifully with movement – ideal for an aperitif on the terrace or dancing until morning. During the day, it pairs successfully with linen trousers or a skirt; in the evening, it works in a duo with a long cardigan and minimal jewellery.
The Moonlace top can transform faster than you change your plans for the day. Decorative rings allow the fabric to be draped in different ways, adjusting the character of the look:
The top works as a closed upper piece for lunch and as an open bandeau for a pool party. This is not magic, but a carefully considered model from the 2026 summer collection by 25 Union.
A skirt is a versatile piece in a cruise wardrobe. It easily changes the mood of the look depending on the chosen top: during the day, it is paired with a minimal top and sandals; in the evening, with a cardigan and expressive accessories. In the 2026 knitwear collection, we have brought together models that cover every scenario: from a morning visit to the pool to an evening dinner on the terrace.
Liora is a wrap mini skirt with an adjustable fit achieved through soft ties, ensuring comfort throughout the day. Women's summer clothing with an asymmetrical cut makes the silhouette more dynamic, adds a touch of casual ease to the look, and visually elongates the legs – ideal for a cruise wardrobe, where every detail should enhance your appearance. Pair it with a knitted top, shirt, or swimsuit – Liora will fit equally naturally into a walk along the promenade, relaxation by the pool, or a city date.
The lightweight cotton fabric of the Eneya skirt by 25 Union flows softly with every step, creating a silhouette associated with carefree summers by the sea. The statement ruffled waistband delicately emphasises the waist, adding femininity to the look. Simply complement the skirt with a minimal knitted top and sandals – and the question of what to wear on a summer date is instantly solved.
The Luna convertible skirt is designed for a dynamic rhythm. The model changes its length, fit, and character through a single element – a wide double waistband. Styling options:
The seamless viscose knit flows softly, creating an elegant silhouette without unnecessary volume. One skirt, three lengths, stylish looks. On a cruise – exactly what you need.
A cruise wardrobe would be incomplete without a pareo skirt that transforms a beach look into a more elegant one in seconds. The Fluida model is made from lightweight cotton knit that drapes beautifully and allows you to feel comfortable on a hot day. The slight transparency of the fabric adds airiness to the look and emphasises a tan.
The Fluida pareo skirt by 25 Union:
With a swimsuit from the same collection, you can create a complete beach set or a look for a poolside photo shoot. And when worn over a top and trousers, it creates a relaxed urban look.
Beach dresses and elegant summer styles are the heart of our 2026 cruise wardrobe. They require no thought about combinations and instantly transform a look from daytime to evening. In the 25 Union summer collection, knitwear reveals itself in a new way: it flows beautifully, softly follows the silhouette, and makes every model expressive and truly comfortable. The dresses are not tied to a single scenario. In the morning, they accompany you to breakfast overlooking the sea; during the day, on a walk through old streets; and in the evening, they become the basis of an outfit for dinner on the terrace.
In a cruise wardrobe, Vira takes the classic bandeau and adds sophistication to it. The textured knit creates an elegant pattern that works as a decorative element in its own right. The drawstring at the neckline provides full control over the cut. Wear the Vira dress according to your mood:
Tie it around the neck to create elegant vertical lines, or lower it for a classic bandeau style on a hot day. With Vira, you will not have to think about which dress to take on a seaside holiday, because it adapts to you.
Cruise aesthetics are built on details, and in the Sole dress, this role is played by the geometric cut. A deep neckline at the front and a triangular cutout at the back create a play of exposed areas: the vertical lines visually elongate the silhouette, while the statement geometric details add a graphic quality. The model looks particularly flattering with:
By pairing it with a lightweight cardigan or jacket and heeled sandals, you can easily create a layered evening look or a cocktail outfit. Without further ado, Sole is among the best evening dresses for summer.
The Selene dress does not require bright accessories, as the main accent is already built into the silhouette. The one-shoulder asymmetry and semi-open back create an expressive look while maintaining a balance between elegance and sensuality. The contrast of textures is carefully maintained here: a structured top and an airy ruffled bottom. This is the ideal women's summer clothing for dancing until morning on the deck of a cruise liner or walking along the promenade in the sunset light.
Echo solves the question of which dress to take to the seaside in one go. It is a cover-up model that transforms easily. Thanks to the deep openings under the arms, the straps can be pulled over the head, changing the silhouette from relaxed to asymmetrical. With Echo, there is no need for numerous beach dresses; one model creates several looks: an airy outfit for walks by the sea, a striking cover-up over a swimsuit, and a base for an evening set with statement jewellery.
Calypso is made of textured cotton knit that beautifully lets the light through, creating an expressive play of textures. The look is built on contrast: a restrained closed front and a deep oval cutout at the back. The dress solves the problem of what to wear over a swimsuit at the beach and also works as an evening outfit. The model is available in two lengths:
Both options retain the signature cut and character. They can be paired with a swimsuit, knitted top, or minimal bodysuit to reveal the dress from our 2026 summer collection in a new way each time.
Another of the best evening dresses for summer is the Theya model, which looks luxurious and reveals feminine sensuality through its cut. Soft draping in the décolletage area ensures a comfortable fit without transparency, while the deep cutout at the back delicately reveals the line of the spine. The semi-transparent viscose structure softly envelops the body, creating a weightless effect. Paired with a maxi cardigan, the Theya dress creates a layered evening look. With heeled sandals and a minimalist clutch, it becomes a cruise-inspired outfit for cocktails on deck.
Women's summer clothing in a cruise wardrobe should be lightweight, breathable, and expressive at the same time. The Leya openwork midi dress by 25 Union meets all three requirements. The weightless texture makes the look voluminous and lively, the open back adds lightness, and the high side slits create movement while walking. Leya is a model that looks equally good as a beach dress and as an outfit for parties or a poolside photo shoot. The piece works as a statement on its own – simple sandals or minimal accessories are enough to complete the look.
The Maris cotton set is a ready-made formula for the cruise summer of 2026, where all the elements are already in place. The jumper and shorts, brought together in an openwork set, create a complete, thoughtfully designed look for a summer holiday. The knit texture adds depth while preserving a sense of lightness even in hot weather. The relaxed silhouette looks equally convincing by the sea and in the city.
What to wear it with for maximum effect:
Maris is not just women's summer clothing. It is your mood for the entire holiday. Light, romantic, flawless.
