In reading the reviews I do agree that along and near the arm pit seem to be big. I weigh 111lbs, 34b and 5'7". I had ordered 5 for my work shirts to be screen printed. As I tried the first one on, it was perfect. Tried the rest on and two out of the five had the problem listed above. So I will return the two and hope when they send my replacements they will fit correctly. I feel that these must be all "seconds" and that is why they can sell at a cheaper price. Try NB in small as the same style shirt does not have this issue.I ordered this tank thinking I was ordering the same style of tank that I had previously ordered. It is extremely baggy. I ordered a small (I am 5'5", averaging 118-122 lbs, slender but athletic build). I wore this during a crossfit WOD were we did handstand pushups and I should have just taken this tank off because I was worried it would fall off while I was upside down. I will definitely only be wearing this tank while running.**UPDATE: I would like to update that now that I am 25 weeks pregnant I am so glad I kept this tank top. It is one of two tanks I currently own that still fit over my baby bump and has been a lifesaver during WOD's the past few weeks of our lovely hot and humid summer. If you like loose fitting workout tanks or if you are pregnant this is a good option for you.I bought this and ASICS Women's Circuit 7 Singlet at the same time. The fabric is light weight in both of them but the arm holes are cut larger than any other normal woman's singlet. It kinda feels like they were trying to get the same effect as a men's singlet ( more open on the arm hole for air circulation ) but to me it just feels weird. The ASICS Women's Circuit 7 Single is a better cut if you like it more snug around your arms and you aren't layering.This is a great workout shirt for the price, it breaths well and is not too tight. But the arm holes where huge! They left a large gap underneath my arms that was not attractive. I fixed this by taking it in under the arms. It was a quick and easy fix and looks much better now. Over all it is a good for working out, but having to alter it straight out of the package was annoying.I ordered this in several colors and I am pleased overall with the product. The material is nice and airy and very comfortable. They are cut higher than most of my workout tanks, at the neck and in the underarms, but that doesn't bother me. My only complaint would be the inconsistency in sizing from one color to the next. None of them are cut quite the same.I'm generally between small and medium, fits a little snug if you're a little big on top. I ordered white and it's not too shear, it's what I wanted for the summer and to match some multi colored shorts. I will keep it and I may order another one in medium in another color.I am 5'3" and 115 lbs. I have broad shoulders and usually wear a medium in shirts. I read that this shirt runs big so I got a small. Well, it's still too big. I love the style and look. However the arm holes gape open. I had thrown the packaging away so couldn't return it, so I wear it as a night shirt which is great because it is lightweight, cool and comfortable.I love this top for warm-weather cycling. I bought the large when I am usually a medium to be sure it was roomy and breezy enough, but it is quite long on me (granted, I am short). I may eventually hack some off and shorten it myself, though the extra length does help cover up black bike shorts, which get so hot at times.Super cute and comfy fit and fits exactly how I wanted it to! It’s meant to be a bit of a looser fit I think so it’s not spandex-y skin tight.J’ai commandé ma taille habituelle et cette camisole était tout de même VRAIMENT petite. J’aurais du commander deux tailles au dessus mais sans ce problème, la camisole est de bonne qualité pour le prix.I love the material. It is weightless and very comfortable when you move around.But I have a lean and long torso, the chest is still too big compare to other brands same size. Also, the tank is long (as shown in the picture).No es tan amplía como lo dicen , creí que me quedaría más amplia y no fue así , me la quede por precio , me hubiera gustado un poquito más suelta ...Love it! I sized up to a medium and fits perfect. I’m 130lbs and 5’4.
