This shirt is overpriced. It's a cheap quality fabric and the collar is not as nice as in the picture. Brooks Brothers makes a similar shirt that is much, much better!

Very cute suit, however, this is best for a small-busted woman as there is no support whatsoever.

I’m a 36C/10-12 and bought a large hoping it would fit. Wayyy too small, would need probably 2 sizes bigger. Super cute though, I’d definitely exchange if they offered anything above large.

Other reviewers said it runs big, so I thought a large would be good for me (I’m a 10/12). Yikes, was it too small! Super cute though, I’d definitely exchange if they offered anything above large.

Fits amazingly on my petite frame (A- cup and I ordered an XS). This is a great option if you have a smaller chest and need a bikini top that won’t gape open when you move or bend! Very nice quality.

So cute! I’m 5’4” & large busted (34DDD) and this swimsuit actually works in medium for me. It didn’t rise up too high on me but if I was taller I can see how it would. It’s really stylish.

I really wanted to love this swimsuit but unfortunately I couldn't get pass the material and overall fit. Pretty see through, if you have any body fat, it will show every imperfection. Basically you need to be extremely thin and zero body fat. Also, the chest area is not very supportive, it drags your boobs down, not flattering at all. If you are 32 A in bra size, this suit is for you.

This is the cutest bathing suit! I really wanted it to work out but it is extremely high cut on the leg and was a little too revealing for my body type. So disappointed.

I ordered this item in a small and x-small. I am a size 24/25 waist and a bit cheeky so I wasn’t sure which would fit. Ultimately I went with the x-small. The style and material are beautiful! Such a cute and unique suit - can’t wait to wear! For the top, I ended up with a small. I’m a 32 B and felt the small top fit me better.

Love the style but it runs very large. Size down from your normal size and if you are a true XS these XS bottoms will be a bit baggy on you.

These fit SOO big. I am always a SMALL in swimsuits and I had to return for an XS, and even then I felt that it wasn't that fitted. But really soft, comfortable and beautiful style. I wear a 24 size jeans, and usually wear a SMALL in Kiini, Tori Praver, Solid & Striped, and Marysia.

Too skimpy in the rear end and leg openings for me. I’m 56 yrs old 5’7” 135 lbs. But it’s a nicely made swimsuit with dark lining and beautiful colors. Wish it covered more. It’s going back.

I am 5'4", 120 lbs, 34B and I initially bought a small, and hated the fit. Because the back was so beautiful, though, I decided to give it another go in a different print and in a medium and it fit perfectly. The material is strong, is flattering, comfortable, and really well made. I think this would work best with smaller-chested women, however, as it doesn't give chest support.

I love this suit. Great classic one-piece. I did size up because my torso is a bit longer and it fits fabulously. I always receive a lot of compliments on the suit.

Way to small definitely size up. I am 5’5 125 34C and a large was way small in the top and torso not long enough. No support in chest either so unless you have breast implants or a very small chest, it will not look right. The back is beautiful.

I desperately wanted to love this suit. I love the color, design and that the padding in the bra was light. I'm 5'8" and felt like I needed 3" more in length. The top of the suit came to the middle of my bosom! If they had this suit in long, I think it would be perfect. Alas, it's going back.
