Love the fit!
Love the fit and feel of this tank. Feels casual yet classic. I wish it came in more color/print options. A red stripe or a green stripe would awesome! I am 5'1" and 165 (large chest) and a large fit perfect!

Love the print, but didn't like the style...
Size: Small, Color: Dark Camel Leopard
I'm 5'5 114lbs 34B and got the "camel" leopard print in size small. I think it's technically a cute shirt and it fits okay, I guess, but the style and color ended up looking terrible on me! For reference, the size small measures 21 inches long (from the center of the front collar to the bottom), and about 18 inches wide. I find the style really unflattering on me.
The color seemed like it would be flattering for most skin tones, but it ended up making my yellowish skin tone (I'm half asian) look sickly. Also note that this shirt is made of rayon, which is sensitive to heat, so if you get it (and you like it) you should keep it out of hot water and avoid putting it in the dryer if you don't want it to shrink.
As for the fit, I usually wear size small unless I want my shirt to fit oversized or flowy etc, so I got this in small. It fits loose enough to be comfortable, but this type of collar is so unflattering on me (I could deal if it was either higher or lower) and the curved hem and in-between length just doesn't suit my body type. LOL, apparently, the fact that it has a cool print still doesn't change the fact that the "muscle" tee style looks terrible on me.
It might suit someone else though. The fabric is stretchy and soft, but it's not clingy or see thru (might be in other colors though). The armholes also don't gape at all (doesn't show any of my bra). I ended up having to return it.

Perfect Summer Tank!
Size: X-Large, Color: Black
I recently added the Amazon Essentials Relaxed Fit Sleeveless T-Shirt to my everyday wardrobe, and I’ve been pleasantly surprised by how versatile and comfortable it is.
Fit & Comfort:
True to its name, the relaxed fit is roomy without looking baggy. It’s ideal for casual wear, working out, or layering under jackets and cardigans. The sleeveless cut offers great freedom of movement, and the armholes are well-designed—not too tight and not too loose. It’s flattering on different body types and long enough to cover the waistband comfortably.
Fabric Quality:
The cotton blend is soft, breathable, and holds up well in the wash. It’s not too thin or see-through, which I appreciate. It also doesn’t cling, making it perfect for hot days or light workouts.
Style & Versatility:
The design is simple but stylish—easy to pair with leggings, shorts, or jeans. Available in multiple colors, so it’s easy to stock up for mix-and-match options.
Price Point:
Great value for the price. It's budget-friendly without feeling cheap, and it performs just as well as more expensive basics from other brands.
Minor Cons:
Some lighter colors may show sweat slightly more.
If you prefer a more fitted look, you may want to size down.
Final Verdict:
The Amazon Essentials Relaxed Fit Sleeveless T-Shirt is a solid everyday staple—comfortable, affordable, and stylish in a low-key way. Whether you're lounging, running errands, or hitting the gym, this tee gets the job done.
