I bought this for a special occasion, but I haven't had a chance to wear it, so I'm putting it up for sale. I purchased it two years ago and have only worn it twice. I wore it with navy tapered pants. It looks polished when paired with a cardigan that is the perfect size for the jacket's inner layer. The frill sleeves nicely conceal any concerns about the upper arms. It has a lining, so it's not see-through even when worn alone. The inner lining is stretchy, but the outer fabric is not. - Material: Main body/100% polyester, other - Size: F (fits like S~M size) - Length: 54cm, Bust: 91cm, Hem width: 102cm, Neck width: 22cm (Please note that these are amateur measurements) It's a pullover blouse that you wear after unfastening the button hook. I will ship it compactly, so please be aware of any folding wrinkles.
