These stretchy leggings are made from high-quality silk thread that is supple and moist. The rise is deep and loose enough to cover your belly button. On the other hand, the ankle part does not sag and looks smart even when peeked out from under the bottom. The length is longer than previous silk leggings, reaching ankle length. The smooth and comfortable feel of high-quality silk. I would be happy if you could wear it as a base for bottoms. Please see the product page for details.
