A couple weeks ago at Goodwill I picked up this pattern:
Quick Butterick 6504. I don’t know what year it is from, but based on the price I would guess the 70’s.
The reason this pattern was such a good find is that when I checked the envelope to make sure all the pieces were in there (I never used to do that, but I have bought a couple awesome patterns, only to find out that they were missing key pieces, so now I always check.) not only were all the pieces in there, but all the pieces for BOTH sizes were in there. I just got 2 patterns for the price of one! Plus it only uses about a yard of fabric and looks super easy!
