This is a top from the Russian ballet wear brand Ballet Maniacs, made of stretchy material with lovely lace. The size is S. It's a slim fit, so it's recommended for slender people. It's no longer listed on the website of the Japanese distributor, but I believe the purchase price was around 14,000 yen. (For reference, a simple stretch tulle top is sold for 11,160 yen.) When layered over a simple camisole leotard, the delicacy of the lace is highlighted. This product is made overseas. I remember purchasing it in the fall of last year through an order at a sales event. There are fold lines from when it was sent to me, but I don't think it will affect wear. ● Please be sure to check my profile before making a purchase.
