I was looking for a basic tight long sleeve shirt to wear under my scrubs and this is the perfect shirt. Perfect thickness for layering, not too see thru, and its tight enough to roll up the sleeves to 3/4 length without cutting off my circulation. Its long enough to tuck into my scrub pants. Its also really stretchy! The neckline also isn't too high, but you can def see it when I wear a v-neck top. For fit reference Im usually a small/xsmall in tops, bra size 32D, 58 130lbs and I got a small. I will be buying more!
