I couldn't re-cut, I had no more fabric, so they got little pieces added at the front [narrower]
The peplum pieces are drafted in one curve, and looking at the original pattern source, you don't really relate it to front/back measurements, just to total waist. My scaled down draft worked out fine form the instructions, no idea what RH did! By all the other errors that either I've found, or others have told me about, she is just crap at drafting and should not be putting these things out untested.
I will continue the search for the perfect blouse match. Someone on my blog suggested blush pink, but I don't really do pink!
