I have wanted to buy swimwear from AQUX for a while and I am really glad I finally did. I felt so sexy immediately when putting these one, I can't wait to show them off at the pool! They fit tight, so I may size up on my next order. FYI, I am around 140 lbs (~63 kgs) and have a 32 in (81 cm) waist. I got a medium and it is quite tight! No worries for me, I find a super tight swim brief to be great :) Also shipping to the US was super fast and easy with AQUX, I was worried at first with covid shipping regulations, but there were absolutely no issues and it arrived very fast and discretely.
