For most men, the best-fitting swim shorts are the short-style variety, measuring 35 to 40 cm in length, with an elasticated waistband featuring a drawstring and an inner lining: they look good on almost any body type, are suitable for both the beach and the beach bar, and dry quickly. Swim briefs and boxer shorts are ideal for swimming or for a more even tan; Bermuda-style swim shorts are best if you’re looking for more coverage.
Updated on 15 November 2026 · The Gerry St. Tropez team – swimwear since 1968.
At Gerry St. Tropez, we have been designing Mediterranean-style men’s swimwear since 1968. This guide summarises what we see every summer in our shops in Barcelona, Platja d’Aro, Cambrils, Ibiza and Formentera, based on actual figures from our collection.
Types of men’s swimwear and what each one is for
| Type | Inseam | Ideal for | Points to bear in mind |
|---|---|---|---|
| Short swimsuit | 35–40 cm | The beach, the swimming pool and a whole day out | The most versatile: it flatters almost every body shape |
| Bermuda-style swimming trunks | 45 cm or more | More coverage, long legs | It weighs more when wet and takes longer to dry |
| Swimming trunks | 10–20 cm | Swimming and playing sport | Fitter fit; please choose the right size |
| Briefs | Without a leg | Swimming and a full tan | Compulsory at some public swimming pools |
What length of swimming trunks should I choose?
The length makes a big difference to how it fits. A simple rule: the hem should be above the knee, mid-thigh. If you’re under 1.75 m tall, a shorter length (around 35 cm in size M) makes your legs look longer; if you’re tall or prefer more coverage, go for around 40 cm.
Our current collection features two feature-length films: 26 models measuring around 40 cm and 10 measuring around 35 cm (measured in size M/44). The exact length is given in the description of each swimsuit.
How to choose the right size
- Choose your usual trouser size: our swimwear ranges from 42/S to 52/3XL.
- The elasticated waistband with an adjustable drawstring gives you some leeway: if you’re unsure between two sizes, the smaller one usually fits better on the leg.
- Take a look at the inner lining: it provides support without being too tight and prevents chafing on a long day at the beach.
What features make a good swimsuit?
- Lightweight, quick-drying fabric: walk from the water onto the terrace without getting soaked.
- Drainage holes at the back, so that the water can drain out and a bulge doesn’t form.
- Side pockets and side openings that allow freedom of movement.
- Long-lasting colour: At Gerry St. Tropez, the colours are dyed and the prints are designed to last for several summers.
All these details can be found in the Gerry St. Tropez men’s swimwear, both the plain such as the prints (seersucker stripes, crabs, corals, flowers…). They cost €95 and delivery is free on orders of €130 or more in Spain, the EU and North America.
Plain or patterned
A plain swimming trunks in navy blue, white or green goes well with any linen shirt or polo shirt, and is a safe bet if you’re only going to have one. Small prints (mini-floral, checks, small stripes) are the easiest way to add a touch of personality without being too flashy; large prints are for those who’ve already got the basics covered.
Frequently asked questions about men’s swimwear
Which men’s swimming trunks are the most flattering?
These short-style swim shorts fall to mid-thigh (around 35–40 cm long in size M). They make your legs look longer and suit almost every body shape.
What length of swimming trunks is best if I’m short?
A cropped pair, about 35 cm long in size M. They show more leg and create a slimming effect.
What is the inner lining of a swimsuit for?
It provides support, prevents chafing and means you don’t need to wear underwear. It should be soft and not too tight.
How do you wash a swimsuit to make it last?
Rinse it with fresh water after each swim, wash it by hand or in cold water, and dry it in the shade. Chlorine and direct sunlight are what damage it the most.
