This is a set of a small floral print camisole and cardigan. They're cute worn together, and also cute worn separately. You can enjoy them in various ways. The fabric is thin, but I don't think either the camisole or the cardigan will be see-through unless you're wearing a brightly colored item underneath. I bought it new on Mercari about a year ago, and wore it about twice last year, but I don't think I'll wear it this year, so I'm selling it. As for the size, it gives me the impression that it's a little big, and I'm 155cm with a "skeleton wave" body type. The fabric stretches well, so I think most people will be able to wear it without feeling tight.
