If you're a petite plus-size lady, you probably have difficulty with overly-long shirts. Instead of swamping yourself with an overly long top, make it a dress. It's the fastest summer solution and you can avoid the tailor, too.
The Solution: If you can't bear to wear your shirt as a dress because it feels too weird, slip into a pair of slim-fitting bermudas beneath.
