The frill design on the sleeves makes your upper arms look slimmer. The armpit area has a sturdy fabric underneath, so it's difficult to see through. It's a beautiful color and very cute. I've only worn it a few times and it has no noticeable stains. ● Size: Marked M Length is 57cm, width is 50cm. ● Condition: Please understand that this is a used item and has been stored at home before purchasing. ● Other notes: Shipping will be via Mercari delivery or regular mail.
