Girls Must Have - Couture swimwear for all women
Girls Must Have is a swimwear maison designed in Switzerland and made in Europe, where couture-inspired cuts, premium materials and attention to every detail come together to accompany women through all stages of their lives.


A maison born from women’s gaze
Girls Must Have was created from the experiences, stories and needs of women.
Before drawing her first swimsuit, Alexandra listened to her friends, models, women around her - those who love fashion, and those who couldn’t find a swimsuit in which they felt truly themselves.
From these conversations emerged a clear intention: to design swimwear that combines style, comfort and, where necessary, discreet technical solutions, without ever reducing women to a size, a scar or a label. With or without prosthesis, with or without scars, with or without complexes - every body deserves a beautiful swimsuit.


The Girls Must Have signature
Certain codes are found from one collection to the next:
- couture-inspired cuts that structure the silhouette,
- refined details such as bows, flounces, gatherings and drapes,
- generous, enveloping lines that flatter the body without constricting it,
- prints that tell stories of travel, light and architecture.
Each model is designed like a small couture piece: a silhouette, an intention, a gesture.
A meaningful alternative
The brand speaks both to fashion lovers and to women who are looking for a swimsuit that respects their story.
Those who want a strong, singular piece for their holidays.
Those who have undergone breast surgery and no longer recognise themselves in medicalised or overly basic models.
Those who want to be able to choose, depending on the day, whether to wear a prosthesis, a cup, or neither.
Girls Must Have positions itself as an alternative that makes sense: premium, beautiful, technically precise when necessary, without ever reducing women to a single category or a single story.


A swimwear wardrobe to wear also in the city
Girls Must Have swimsuits are designed to be worn on more than just the beach.
The one-pieces slip under a skirt, trousers or shorts and become bodysuits for day or night. Bikinis can be styled with linen pieces from the beachwear line for a complete look, from sun lounger to bar, from beach to dinner, from city to countryside.
Each piece is thought of as a versatile wardrobe item, that you will want to style and re-style, from one destination to another.
A European maison
Girls Must Have collections are designed in Switzerland and produced in Europe, in carefully selected partner workshops.
The fabrics are Italian, chosen for their hold, their softness and their ability to stand the test of time.
From the first sketch to the final fitting, via pattern-making, prototyping and production, each stage is carried out with the same requirement: to offer swimwear that combines elegance, comfort and durability - right up to the moment the swimsuit finds its place in your suitcase.
