Because every outfit deserves a good base layer, we crafted our Second Skin High Neck Bodysuit out of a supportive, yet soft, blend of nylon and spandex. It's also ultra-breathable with a high neck, high cut leg opening, and thong back to disappear under clothes. Once you experience the comfort and versatility of our Second Skin High Neck Bodysuit, you'll never want to wear anything else. Approximate measurements lying flat: Pit to pit: 14.5” Length: 26”
