I purchased this long-sleeved collared dress from La porte demain at United Arrows. It has a back zipper and is lined. The collar is detachable with buttons. It's made of a wool blend and is very warm. I bought it a few years ago and have worn it about 10 times. It has a slightly worn feel, but there are no noticeable stains. It has an elegant shape, so I think you can wear it in various situations (о´∀`о) I look forward to your order if you understand that this is a used item! I plan to compress it for shipping. Please understand that there may be creases from folding during packaging m(._.)m - Color: Navy - Size: 36 - Collar design: Corduroy collar - Sleeve design: Long sleeve - Pockets: Front pockets - Length: Knee-length Thank you for looking.
