This is a set of a simple and sophisticated Theory long-sleeved knit top and skirt. "Knit Top" - Brand: Theory - Size: S - Design: Side slits "Skirt" The back is longer in design. It is made of lace material and has two layers. The waist is made of elastic material, but it's a bit stiff. It's a very cute design, but I'm selling it because it no longer suits my age. I think it's best to wear it as a set. Thank you for looking.
