This surprisingly slinky one-piece is basically a bra and panty in stockinette, connected by a sexy open-work mesh bodice. The back is completely mesh, except for the bottom. The top ties for a push-up effect at the empire line, and there is an open keyhole from waist to bust. The center drawstring will slide easily through the holes to make the bust of the one-piece more fitted - just be sure to leave openings where the pattern indicates when working the final row of inner crochet around the edges of the center bust to allow for the center drawstring.
