Lovely colours and design
Lovely colours and design, soft fabric. I'm a size 16D bra, very short torso. Size 16 in the Xover one piece felt quite snug at first, but I was amazed how comfortable it is to swim in, and HOW MUCH FASTER I WENT!!!! Must be more streamlined.

Size up by two sizes if you have big shoulders
I think I might have finally got my sizing correct with Kozi ….definitely size Up by at least 2 sizes if you have big shoulders and upper body. Glad I can now get back to doing my laps and love the quality fabric and how it feels in the water.

Fit brilliantly, feel fantastic
I am loving my new X-over one piece. No more adjusting the top after every block. Was worried about the size but followed the sizing advice and went up a size. End result is they fit brilliantly, feel fantastic and look good.
