I found this dress at a thrift store and thought it had potential, but it was too long and slightly boring. So I shortened it about 5 inches and added some ribbon to the side using a small grommet set I picked up at Walmart for about $5.
First image is the before. I put the dress on and pinned where I wanted the top and bottom of the lace to be.
Unfortunately, it's still fairly plain and I'd like to add some lace to it in the future.
All you need are old t-shirts and 45 minutes :)
