I have been a die hard Lululemon & NOBULL fan for years, and the vast majority of my workout apparel comes from those two brands. I've tried a few Amazon activewear brands with minimal luck, and did not have high hopes for this top initially, but wow, what a great find!About me: I am tall (5'11"), around 160-165 lbs, athletic build, and I like a semi-cropped tank that hits at the waist with a high-rise legging. I am very picky about tops because the majority of activewear is not made for people of my height, and most things are too short. I am relatively lean and like things fitted, so I bought a size Small in the olive green color. The fabric is unbelievably similar to the Lululemon fabric -- it is brushed, soft, flattering, and extremely comfortable. The fit is great-- maybe a TAD snug, but I feel like if I sized up it might be too loose, and I'd rather have things a little more fitted. The top is not too low, not too high, and hits at just the right part of my waist -- in other words, it is almost perfect, and at such an incredible price and so many colors!If you're in between sizes, I would say size up. But honestly, for this price, just get both sizes and return what doesn't work, because you cannot beat the price point. Super comfortable to work out in, flattering, great colors, super affordable! Love this find!
