Description from Knitty.com:
A modern-day corset, Vicky won't give you a wasp waist, but she can be worn at home or out on the town. Sizing is variable based on the wearer's ribcage measurement and cup size. Knit in one piece, Vicky gets her slinky shape through use of varied pattern stitches and short rows. She can be lacy for the traditionalist, streamlined edges for the minimalist, or faux fur for fun!
