Got me out of my comfort zone!
Turned out to be the most comfortable and best suit for lounging and swimming off the Italian coast. This was my first “cheeky” suit and I am now a convert! Plus the fabric is thick and well-made so you feel like everything stays in its place!

Fits fantastic
Very comfortable and great for all water activities. I wear for scuba diving. Easy to get in and out of, elastic is nice and snug, with a great cut. This is my 2nd one piece I've ordered and not disappointed. Well made and easy to take care of.
