GRL One-Piece Occasion Dress Worn only once after purchase. The design and embroidery on the sleeves, and the elastic waistband under the bust are cute! I didn't feel uncomfortable even after eating a lot. The belt is the type that attaches from the top (removable). A petticoat is not included, but the inner fabric is sturdy, so it wasn't see-through. I am 161cm/45kg and wearing a size S.
