These thermal tops are high-quality constructed, stretchy, and form-fitting. Order a size larger: I'm glad I did! I wear a small size in women's tops and wear a medium in junior's tops. I made the right decision by purchasing a medium! I've been looking for thermal tops EXACLTY like these to go under my summer tops in order to winterize them. These thermals are perfect for that because they won't add bulk. However, if you want to wear them on your own and are shy about a less than lean body then order two sizes up. You can definitely see a bra and large navel through these thermals. I ordered black, brown, natural and eggplant. The colors are right on the money! I may even order extras in case I stain my sleeves! LOL!
