This is a thin, short-sleeved dress. It's a size M-L. I tried it on and had the length altered, but I ended up not using it. It has a very loose silhouette. It doesn't constrict the body, so I think it would be very comfortable to wear even during pregnancy. For a non-pregnant person who is 155cm tall, the hem would cover the knees. It has pockets, which I think is convenient. Sleeve Length: Short sleeve Skirt Length: Knee-length Season: Spring, Summer Condition: No stains, tears, or odors
