Very basic and comfortable.
Size: X-Large, Color: Light Heather Grey
This is the kind of shirt that I live/sleep in warm weather at home. Very basic and casual which is what I wanted. Definitely wouldn't call it "trendy" though. Great for working out, lounging in, cleaning in, even sleeping in. The fit is comfortable and loose but be mindful of your size selection. I always have to size up for most of my shirts because my upper arms are larger so some people might think this top is runs big. It does have a higher than usual amount of stretch compared to regular cotton t-shirts due to the higher percentage of spandex. Not much of a color choice available but the gray that I got looks like the pics. It's an ok value for the money but not what I'd call great and they definitely need more color choices.

Perfect Everyday Tank – Great Value and Fit
Size: X-Small, Color: Navy White Placed Stripe
This sleeveless muscle tank has quickly become a staple in my wardrobe. The material is soft, lightweight, and doesn’t wrinkle easily — perfect for everyday wear. I really like that the armholes aren’t too large, so there’s no bra showing. I got the navy and white striped one, and it’s not see-through at all.
At under $10, it’s a fantastic value. I find myself reaching for it again and again. It works great on its own in summer or hot climates, and also pairs nicely with a cardigan or jacket. Looks great with denim shorts or jeans. I am 5’3” and 116 lbs. I ordered the XS and it fits great.

Soft Tank Top
Size: Small, Color: Bright White
Very soft material and comfortable and fits true to size, but the size is flowy/oversized or “relaxed” as they call it. If you want a tighter fit, size down. Perfect for layering.
