One fan wrote: “What is worse than wearing a sweat-soaked t-shirt? In my opinion, not much. I was looking for a shirt to wear while working in the yard, doing stuff that makes me sweat, etc. I am on a medication which causes hyperhidrosis (excessive sweating). Literally, if I THINK too hard, I sweat ... so I had to shop around for a moisture-wicking t-shirt that would dry fast. This t-shirt works as advertised and is true to size. It’s a bit silky but still looks like a t-shirt and is totally opaque (I purchased the black one).”

Whether you're preparing for cooler weather and need to add some layers to your wardrobe or just need a couple of solid undershirts that can also be worn solo, you can't go wrong with the Amazon Essentials slim-fit tank. Sold in a two-pack, these scoop-neck tank tops are made from a blend of breathable cotton, stretchy spandex, and soft modal for ultimate comfort. Amazon customers give them an impressive 4.6 stars overall, and several commented that they're great for people with bigger busts.

One fan wrote: “Exactly what I was looking for. I like to layer a tank top under my shirts as an extra layer. These are well made, fit great, and wash and dry well. I bought them in black, size small. I am five feet tall and 130 pounds and have a bigger chest, and these tanks don’t look over-stretched in them. Will be buying more in other colors! They are not racerback so you can also wear alone and not have your bra strap show.”

One fan wrote: “Not bulky and fits great under tshirts or sweaters without unsightly seams. Arm length and waist length are both great. Neck is comfortable. If I was wearing this alone, I’d probably order one size up so it wouldn’t be too tight looking in breast area, but that’s my style and comfort level (I’m busty).”

One fan wrote: “True to Size fit, I bought an XL, and it's a little longer than some other brands that I ordered for comparison. It comes with a wash bag and instructions. Hint: cold water, delicate cycle, hang dry, easy! For the price I think it hits the mark. I needed it to go under a silk blouse that was a little troublesome with gaps between buttons, but this fixed the issue and made the blouse fit better.”

One fan wrote: “I wear this under sweaters or thin shirts. Material fits snug but not like a compression tank, so it doesn’t bunch up. Nice thicker material hits at hips. Full size shelf bra covers everything (I wear a 38d) Also I like the way it fits under armpits doesn’t come down too low, so nothing hangs over the sides. I have been through many of these type of Cammies and this is by far my favorite. I own 7 or 8 of these.”
