1998 McCalls Pattern Adult Sz S-XL #9496 Uncut costumes Halloween

This is a pattern in uncut condition. The envelope is a bit the worse for wear, but not too bad; the items inside are in excellent condition. The envelope doesn't say what size this pattern is for, but the instructions show cutting layouts for S,M,L,XL; and the pattern pieces have 4 cutting lines. I have listed it as "New" in the sense of "never having been used".
