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.

Drapes Without Clinging, Loose Fit, Odd Shoulder Seams
Size: Medium, Color: Forest Green
I bought the medium and it fits well but I probably could have gone with a small (I'm a size 10). I prefer a looser fit so it's fine with me. The fabric is soft, stretchy and drapes really nice without being clingy. The only thing I find odd is the neckline/shoulder seaming. If you put the shoulder seams where they belong, the back neckline drops lower than the front (the pictures show otherwise). It doesn't feel odd and with the dark color it's not noticeable but it's worth mentioning. I got it on sale, so it's a great value if you don't mind having to line dry.
