Okay, so I just got this ATHMILE ribbed knit tee and I'm OBSESSED! The material is this perfect blend of viscose, nylon and polyester that feels like a dream against your skin.
I got the medium (I'm 5'6" and 125lbs) and it fits like a glove - in the best way possible. It's definitely form-fitting but not uncomfortably tight. The ribbed texture gives it such a luxe look that makes it way more expensive than it actually is.
Wore it to work with slacks and got THREE compliments before lunch! It's crazy versatile - dressed up with a blazer for meetings or dressed down with jeans for weekends. The fabric has just enough stretch to move with you without losing its shape.
Only thing to note: runs slightly small. If you're between sizes, size up. And yes, you'll want to baby this shirt when washing (cold water, lay flat to dry) but trust me, it's worth the extra care.
Already planning to buy more colors - this might become my uniform!
