One of my recent thrift store scores was a super-cute Paul Frank sleeveless shirt dress in a very springy madras plaid. The tag said "XS" so I'm not sure why I thought my bigass would fit in it. But it was half-price day, so I figured for a buck fifty, even if it didn't fit, I could turn it into something awesome. Or trash it. Or give it to a stick.
It fit, but the buttons running allllll the way down the front were screaming. "Holy crap! We can't hang on! We're not gonna make it!" Read more about make do and mend - paul frank dress
