I made my first reversible dress for my baby granddaughter back in April. After searching for tutorials that I could easily understand, I found a wonderful and easy tutorial over at polkadot. When I emailed her to ask her what pattern she used, she kindly responded that she never listed a pattern for the dress because she made up her own based off of a regular A-line dress pattern. She also noted that any pattern for an A-line dress should work for sizing. I really like her style in the things that she makes.
I used cotton fabric. But since this was my first try, I used fabric that I really didn't like, in case I messed up. But the dress turned out nice after all.
