A well dressed man is a confident man and a confident man is a successful man
My wife and I went on a 7 day beach vacation and I bought the cassis square cut swim trunk as a “fun vacation bathing suit”. Now, I am a 50 year old, who lives in board shorts so I knew these where much shorter in length and tighter fit than what I normally wear. I thought I would surprise my wife but had her help me pick out the color. The order process was smooth and shipping was fast. I used other reviews to help with the sizing because I did not want too small or too large. I am a 32/33 waist and the large fit perfect. The wearing of the suit- I will be honest when I first put them on, I couldn’t quite do it. I was lacking confidence. It didn’t help that there was a little vacation excitement in the air if you know what I mean. But after a little “alcohol encouragement” I put them back on and boldly walked out on the beach. This swim trunk is great. The fit is perfect. The quality is top of the line, thick material. And the look is spot on. After a few minutes on the beach, the comfort, quality and look made theses trunks the go to trunks for the week. Even though I continued with the mojitos, I did not need them to feel confident wearing the trunks. I would get up before sunrise, put them on, walk out on the beach with my coffee and wear them all day every day. I swam, surfed, SUP, snorkeled and walked the beach in these. Instagram pics turned out great too. I will be buying another pair for next season. I think that these trunks would look great in the Moorea scarf and Amalfi ascot patterns, especially the gardenia pattern.
Embrace your inner style icon
The Cassis swim trunks are bold, perhaps too bold for the masses. The antithesis of the board short, these trunks will allow you to break free from the chains of uniformity and go boldly to the water’s edge in style. Wearing these in the tropics, you’d need only a pair of espadrilles and a polo and you’d be James Bond circa Thunderball, taking down baddies and turning the ladies heads all while being the smartest dressed gent on the playa. Be brave, my friends. A little confidence goes a long way.
Look and feel great!
These are the best swim trunks I have ever owned. They are very high quality. I am 6’3” and about 190 lbs. The XL fits great!
