efla is a brand by Rie Matsuoka (Okari-e). Size: S Color: BEIGE Material: 100% Polyester (with lining) This dress uses vintage satin fabric made of polyester with an elegant sheen. The moderate draping gives a mature and luxurious impression. It's a dress with a beautiful silhouette that highlights the elegance of a high neck and the mature sexiness of a sleeveless design. I bought it a few years ago and wore it about 3 times. Please check image 8 for the size details.
