Sizing Varies, But an Amazing Tee if you get the right size!
Size: Large, Color: Navy
I ordered this in a size Large, my recommended size per Amazon and the size chart, it was so small through the underbust area that I could not wear it. I then ordered an XL and it is huge! The XL is too big everywhere, but especially through the bust! For your reference the bust line in the XL measures 42" pit to pit. I am going to try again to order a Large and see if perhaps I just got one that was sized incorrectly. This tee is so cute. I love the fit, the neckline, the slight flare at the hem. It's super cute and offers a great feminine look and feel. The material is amazing. Super soft, perfect non-clingy drape, opaque, lightweight . . . there's nothing not to love here!

Honest review of the Amazon Essentials Women’s Slim Fit Cotton Tank Top

This Amazon Essentials Women’s Slim Fit Cotton Tank Top is true to size. Nice and soft layering piece. The boatneck neckline gives the top an elegant look. I got the top in tan, white and black because of its simplicity as well as versatility. You need this top in your wardrobe for sure!

Good fit. Inexpensive chic look
Size: Small, Color: White, Size: Small, Color: White
Great fit and very flattering. I am a small and bought a small. After 4 washes it definitely looks a bit worn…I wear it with trousers for work. I will now be wearing it more casually since it looks a bit more worn. Still worth it for the price and comfy. Colors are what they look like online. I’m 5’6 130 lb

Must have basic
Size: Large, Color: Black
I am so impressed with these Amazon shirts! The material is incredibly soft — like that perfect broken-in tee you’ve had for years but without the wear and tear. They’re lightweight but not thin or see-through, and they wash really well with no shrinking or losing shape. What I love most is how versatile they are. They’re the kind of basics that instantly become a staple in your closet — easy to dress up with jeans and a cardigan, or throw on with leggings for a comfy day out. The fit is flattering without being tight, and they hold up throughout the day without stretching out or looking sloppy. If you’re looking for comfortable, everyday shirts that feel amazing and go with everything, these are absolutely worth it. I’ve already ordered more colors!

love the high neck and crop/waist length
Size: Large, Color: Black, Size: Large, Color: Black
This is one of my favorite shirts- not to loose, but not too tight- has some shape built in. I find the shoulders and neck to be fitted well and look neater than some of my skinnier strapped tank tops -which always seem to hang just a little too low, despite my tall body and fuller upper body, so I don't understand- this looks neater and more put together. I teach yoga and can face my class on hands and knees and not give a show- I'm not prude, but it can be distracting to have a shirt gaping open... the cotton, yes, it's going to age quicker than some fabrics, but I like the feel of it, plus it releases odors more quickly. I have both large and xl size- just depends on my outfit and how I'm feeling-i'm in between sizes so the L is a little more fitted, the xl still looks cute, but gives a little room, esp in the waist- its not as flattering, but cooler and comfy for days I need. I think this shrunk/tightened up a bit in the wash/dry, but not a ton (I don't remember, so think it wasn't much, anyway).
