It's Simplicity 8750 and it's got a lot! Bra, undies, half slip, full slip, and I'm sure you could turn the bra and undies into a bikini with the right fabric. The pattern is cut, but all the pieces and instructions are there. It's a size 12, bust 34, hip 36 though I'm sure it could be easily graded up or down as the pieces look fairly basic.
In other news, I'm trying to find a more diversity in sizes for sewing patterns - but no where around me sells patterns. NYC ladies, where do you get your sewing patterns? I can't find any in the thrift shops or craft stores. Bonus points if it's in Astoria.
