Our selections
Our commitment
Swimwear that respects every body and celebrates every woman.


Alexandra Classen, a designer committed to all women
Former model and founder of Girls Must Have, Alexandra Classen imagined a line of couture, premium swimsuits for all women: fashion lovers, and those whose bodies have changed over time.
Her aim: elegant, well-cut swimwear that can accommodate a prosthesis if needed, without ever compromising on style or femininity.


“Discretion”, the invisible signature of Girls Must Have
Selected Girls Must Have swimsuits feature an invisible inner pocket that allows you to insert - or not - a cup or an external breast prosthesis.
Imagined by Alexandra Classen, this innovation lets you harmonise your silhouette, correct an asymmetry or regain a volume that feels like you - always at your discretion.

Premium women’s swimwear: Swiss design, Italian fabrics, European manufacturing
Girls Must Have is a premium women’s swimwear brand combining Swiss design, Italian high-quality fabrics and European manufacturing in Italy. Each piece is created as a true garment: a swimsuit to wear at the beach, by the pool, or as a body under a linen shirt or wide-leg trousers.
Our collections include one-piece swimsuits, bikinis and two-piece sets, as well as a linen beachwear wardrobe - dresses, shirts, trousers and skirts - to create complete silhouettes. Cuts are carefully studied to flatter the body without constraining it, with considered leg openings, enveloping high waists and adjustable straps to personalise support.
On selected styles, our “Discretion” innovation - an invisible interior pocket - allows you to insert, or not, a light padding, volume or external breast form. It is a discreet solution that does not show, but can be felt, so the swimsuit adapts to you, not the other way around.
To learn more about our story, our founder and our choice of Italian fabrics and European workshops, you can explore the pages About, Alexandra Classen, Our commitments and discover all our swimwear collections.
