The fit is very clingy to wear under other tops without having any bulk. The stretch fabric is very comfortable and not tight feeling. Great for wearing under a shirt, or sweater when you want a little more warmth, or for layering with the neckline showing. I bought several colors in the scoop neck. Shoulder seam and sleeve length are great. Wish I would have bought a mock turtleneck when they were on sale. They also come with pants which i did not get.
