We started with a skirt, of course! Are you seeing a trend here? I don't have a before photo, but you can just about imagine it. I'd made it when I was a teenager!
I just laid my pattern piece out on the existing skirt and cut out around it, keeping the original waistband and pockets...bonus! Then I sewed up the crotch seam and the inseam, hemmed it and I was done!
