Overall, I really like it and will keep it. I tried to find a way to contact seller because I had one issue, but that wasnt an option on amazon. The cups are stamped 20, and I bought an 18. The cups are difficult to adjust (and I'm wondering if they are the wrong size) but once in, then seem and look ok. The package I got seemed to have been a return (bag torn, item balled up in bag) so that makes me wonder if the previous purchase swapped out the cups.The underwire does go all the way under your arm, but isn't that noticeable unless I stretch a certain way.I wear a 14 dress and shirt size (ann taylor sizing) but the 18 was fine. I may order another in a different color, and for that might try the size 16.It is flattering and except for the underwire on one one side being noticable here and there, it is comfortable. Easy to get on and off. I would recommend.I am really in love with this tankini. I find it comfy, supportive and sexy all at the same time.I wear a size 18, am 5'9 and wear a 40 K bra. I bought a size 22. I am losing weight but I still find a bikini to revealing, but I was having a hard time finding a one piece. With a one piece if the bust fit then the bottom of the swimsuit was too loose. Or the swimsuit would be to short. I originally purchased this tankini in red. It fit me perfectly as does this one. Not too long so it looks like a grandmother swimsuit, but not too short that it shows my tummy all the time. I think I look 10 pounds slimmer in this suit which I paired with black bikini bottoms. My bust is completely supported with a decent amount of cleavage showing. Decent meaning I find it sexy but I don't feel like I am hanging out there. I am so excited to wear something COMFORTABLE to the beach for the first time in a long time. I bought a size 22. I paired this top with this my new favorite coverup https://www.amazon.com/gp/product/B06XCDCFJW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1.Straps are adjustable but did not adjust enough for me. I am shorter it was a little longer in the strap area than I needed. Cups fit well as they stretch, I wear a 36 DD, and it covered everything.I just got mine, in 20W.I usually wear size 42D, 2X (18-20).It fits well! Underwires are just the right size.Not snug, but not loose...The top looks great on, is lightweight, has easily removable cups,adjustable straps with gold-tone hardwareon the back... The color is as it appears on the model, the fabric is very festive and bright,the style is flattering, I haven't wore it swimming yet,but I will wear this with a black bottom I got separately.I am 5'11", this is long enough. It is shirred so it can fit a short or tall person!Shows cleavage, but not too much, and support is good.As long as nothing goes wrong, I am very happy with this tankini!I recommend!Love that it gave me some support. Bra size DDD so this kind of fit isnt easy to find. Just wish the torso was longer.This was a nice top, if I had smaller boobs and a smaller stomach, I might have been in love with it. I might have tried a size up but to be honest, I don't think that would have done much for me. For someone with a different body type this top might be just right, but seriously just size up.Love the color. Had to return however was an easy process. Order same one just different sizeI love this top. I didn't read the full description so thought bottoms came with it. The top is so cute I just order some black bottoms to go with it and now I have a complete set. Going to find this in another color. The fit is great.
