In need of a new pair of swim trunks? When it comes to swimwear, your safest bet is a classic pair of close-fitting swim trunks. Shorter and slimmer than the puffy, elastic-waisted suits most guys sport, the fit and feel of these will leave you looking taller, trimmer and tanner. And this pair, from J.Crew Factory, looks a lot like pairs that cost three times as much.
