A nice, comfortable t-shirt with a bit higher moc neck
Size: Small, Color: White
I wear tee shirts a lot, but, because I need something a little warmer at times I wondered if such a thing as a moc-neck tee existed. This shirt is soft and comfortable, not tight but more tee shirt- like in fit.

Wash before wearing — the dye will run
Size: Small, Color: Royal Blue
Make sure you wash this shirt before wearing. Maybe even two washes. The color WILL run and dye your skin. (I was impatient and wore it before washing and ended up with a blue torso)
Otherwise, it fits well. I’d put it as a regular fit rather than a slim fit. Very soft, albeit synthetic, material.
