I’m a 5’6’’ 140lbs ish woman and I got a Medium
Size: Small, Color: Black, Pocket Description: Plain Front
Paid 10 bucks ! Got a medium . I am 5’6” 142lbs . It’s thick & 100% cotton. A ‘medium ’ seemed big but I intentionally ran it on high heat in the dryer & it shrunk so it fits me perfectly . The sleeves go closer to my elbows than women’s shirts… which I love. The crewneck is perfect so I can do burpees without worrying about plunging necklines. I wear a 36C bra and this tshirt is comfortable around my chest & shoulders. I carry extra weight on my belly and it’s still comfortable. Absolutely love how it looks on me. It says RELAXED fit in the title so I don’t understand why people are grumbling about the looser fit. I love it — thank you Amazon, for offering 100% cotton clothing

Little bit on the small side
Size: XX-Large, Color: Black, Pocket Description: Plain Front
Run a little small, but the quality of the shirt seems to be pretty good. It is thick and nice. Warm and softness are both good.

Impressed for the most part
Size: X-Large, Color: White, Pocket Description: Plain Front
Going to give it 5-stars for now, well see how well they hold up after a few washes. They for sure feel like nice heavy-weight shirts. I like them alot for that reason. They have a boxy-fit though, so not "fitted" at all but thats fine for me because I am using them as under-shirts.
