This dress was in my closet. I've worn it only once or twice. You could wear a jacket or cardigan over it, and it would be suitable for graduation ceremonies, entrance ceremonies, etc. How about it for a slightly formal occasion? The fabric is for autumn and winter. It's about 10cm above the knee on a person who is 165cm tall. Length: 82cm Simple black long-sleeved dress, size M, with lining. #blackdress #simpledress - Brand: earth music&ecology - Size: M - Color: Black - Design: Long sleeves, with lining Thank you for looking.
