I do love the fabric and the feel of this suit on. For those who haven’t ordered a Coeur Trisuit before-do know that the crotch is not really padded, it’s more so just a couple layers of extra fabric. Which I didn’t mind, however I do know some people who like a little padding in their suits.
I got a medium. I am 5’6 and weigh around 155lbs. I have an athletic build. I measure as an upper end medium, but it fits more comfortable instead of snug and there is no compression. Perhaps sizing down would have been beneficial -too late now with it being a final sale item. What’s also interesting is the “what’s my size?” system recommended a large, but I am very glad I did not go with that. The only thing I really didn’t like is the torso- it is too long for me so I have a decent amount of extra fabric in the abdomen. While that extra fabric doesn’t look good, still everything else about the suit is worth it. Maybe try a size down next time?
