>>4397043>longsleeved jskHeh. JSK's don't have sleeves. A dress with sleeves is callen a one-piece, or OP. Aside from that, I can't really answer the question. Will the shirt be showing in any way? What kind of shirt is it? What kind of dress is it?
I usually wear shirts under my dresses so the skin isn't touching the material of the dress, but those shirts always remain unseen.
