Bikinis and Swimwear: MTHOR's selection of iconic pieces

Welcome to MTHOR's Bikinis and Swimwear collection, where the most desirable pieces of the moment meet the timeless classics of luxury swimwear. We have curated this selection like a true summer wardrobe: triangle bikinis that revisit Y2K codes, sculpting one-piece swimsuits, and of course the most coveted collaborations, starting with the highly anticipated SKIMS x Roberto Cavalli. Every piece is authenticated by our team of experts before shipment, to guarantee you an impeccable product, delivered in its original packaging. Whether you are preparing a stay in Saint-Tropez, Mykonos or simply your next poolside afterwork, you will find here the piece that makes the difference.

SKIMS x Roberto Cavalli: the collab reinventing luxury swimwear

Announced as the fashion event of the season, the SKIMS x Roberto Cavalli collaboration brings together two seemingly opposite universes: the minimalist and inclusive approach of Kim Kardashian's brand and the flamboyant heritage of the Italian fashion house founded in 1970. The result is a capsule designed as a dialogue: SKIMS brings its ultra-wearable cuts and obsession with perfect fit, Roberto Cavalli signs the iconic prints that built its legend — animal, snake, and of course the Fagianella print, a direct reference to the pheasant feathers Cavalli has loved since the 1970s.

At the heart of this capsule, the Triangle Bikini Top Fagianella Print embodies everything this collab promises: a classic triangle cut, reworked with SKIMS' know-how on fabric and support, dressed in the Fagianella print with its warm autumnal tones. An object of desire that sells out within minutes at every restock, and that MTHOR has chosen to reference in this new collection to spare you the obstacle course.

This collaboration is part of a broader SKIMS strategy, multiplying prestigious partnerships (Fendi before, Roberto Cavalli today) to transform its essentials into true collector's pieces.

The triangle bikini, timeless by essence

Born in the 1960s and popularized on the beaches of Saint-Tropez by Brigitte Bardot, the triangle bikini has become one of the most enduring markers of the summer wardrobe. Its minimalist cut — two triangles, two ties — concentrates the very essence of swimwear: let you tan, reveal without overdoing it, adapt to every body type thanks to adjustable straps.

In its 2026 version, the triangle has been transformed. Fine ties replace rigid seams, fabrics gain comfort thanks to last-generation nylon-elastane blends, and prints become real artistic signatures. The SKIMS x Roberto Cavalli collab is the perfect example: the classic triangle serves as a canvas for an ultra-graphic Fagianella print, transforming a basic into a statement piece.

Beyond the triangle, our collection also gathers the cuts shaping the season: balconnets for structure, sporty bralettes, retro one-pieces, or bandeaus that flatter shoulders.

How to choose and wear your luxury swimwear

Choosing swimwear is not just about choosing a size. Here are the three criteria that make the difference between a piece you wear twice and one you keep for several seasons.

Support first. On a triangle, check the quality of the ties and the inner lining. A good piece does not deform after a dive. On SKIMS x Roberto Cavalli, the fabric is designed to hold its shape after immersion, which is not the case for all fashion-luxury collabs (some houses use fabrics meant for the runway, not the pool).

Color and print next. A strong print like Fagianella is best worn as the single statement of the outfit: pair it with plain linen shorts, a neutral sarong skirt, or flat natural leather sandals. Avoid overload.

Size finally. Luxury brands often run small. SKIMS runs quite true on the cup — if you hesitate between two sizes, take the larger one, especially on a triangle where comfort prevails over compression.

FAQ — Bikinis and swimwear at MTHOR

How to verify the authenticity of a SKIMS x Roberto Cavalli swimsuit?

Every piece we ship is checked by our team before departure: labels, print consistency, tie finishes, original SKIMS packaging, hangtag with collaboration mention. We ship with an MTHOR seal that certifies authentication. See our complete process.

Which size to choose for a SKIMS triangle bikini?

SKIMS runs rather true to size, particularly on the cup of a triangle. If you hesitate between two sizes, take the larger one. The reference on the hangtag is European size (XS/S/M/L) and not US. If in doubt, contact our customer service with your bust measurement in cm — we will guide you.

Is the swimsuit delivered in its original packaging?

Yes. Every piece is delivered in the official SKIMS x Roberto Cavalli packaging (signed box, protective plastic pouch, collab hangtag), identical to what you would receive buying directly on the SKIMS site during a drop.

What is the delivery time?

We ship worldwide, with home delivery against signature within 2 to 8 days. You benefit from real-time tracking by email and WhatsApp, whatever your destination.

Will I have to pay customs fees?

No, no customs fees are charged to you. MTHOR covers all customs fees and taxes, whatever your destination in the world. The price displayed on the site is the final price you pay: no nasty surprise on delivery.

Can I return my piece if it does not suit me?

Yes. You have 14 days after receipt to return your swimsuit to us, provided it is in its original state (never worn, hangtag intact, hygiene pouch not removed). The refund is processed within 24 hours of return reception.
