💅geoooooorgous💅 and super comfy
Let me just start by saying how 💥striking💥 this suit is. The red is the most beautiful mix between a deepish brightish red, contrasting oh so elegantly with the black bodice. The suit gives off a 🔥oooooh u so scary🔥 vibe while also being like 🎀she's a princess, have some respect🎀. And the mix of those makes you feel unstoppable both in the pool and out. But with the fit of the piece, I mightve been lucky to be exactly in the middle of my size (10), in the chart, so it fit almost ✨️perrrfectly✨️. The only spot i wish it had a bit more shaping to was the waist as (idk if u can see in the photo) the fabric is a good cm or so off of my skin. But aside from that the fabric is super dooper 🧈smoooooth🧈 and I see lots of other reviews say that it doesnt stretch much, and I guess it doesnt stretch A LOTTT, but for me its 🪄just the right amount🪄 of stretch. If it were to be any stretchyer, imo, it would move around while I swim, which is ✋️NOT ACCEPTABLE✋️. So yeah, hopefully this helps, IIIIIIIII (thats a bunch of i's btw, pronounced like eyeyeyeyeyeyeye) absolutely 💕adore💕 this suit and think if you love these colours (or any of the others, though i haven't bought them), or love the back of the suit which I think is 💖stunning💖, then its defo worth getting. (photos were after a rough set btw so dont judge)

Best Swimwear By Far!!
Awesome pair of swimming togs!!! I’ve tried a number of different brands over the years and Kozii is the best by far!! Love the colour and design. The men’s racer cut feels comfortable and the material is very durable and feels smooth on your body.
