This dress is made of very soft genuine leather. Because it's lambskin, it's incredibly soft and accentuates the body's lines beautifully☆ The stitching is also done by hand, one stitch at a time, giving the dress a nice accent♪ The size is 40, which is equivalent to a Japanese M to L. I paired it with a turtleneck sweater from my own collection this time, but it's a design that can be worn on its own depending on the temperature. Moreover, the lining is made entirely of silk, giving it a luxurious feel and smoothing the skin where it touches. #Tommys - Brand: HIROKO KOSHINO Premiere Lambskin (lamb leather) - Color: Gray - Style: Sleeveless - Length: Knee-length No stains, tears, or odors.
