I had to un-stitch as my sizing guide (my eye) failed me. Once I put it on the mannequin's, I realised that it was to big the bust department. I am happy in a way, that the time wasn't waisted as the seam didn't sit right. Pleased that I hadn't gone on and started the skirt part.
I thought about how I could do the seam differently. I made it two sizes smaller and re- seemed the back.
All in an afternoon;-)
