The package states that the model is 5'3", 105lbs. I am also 5'3", but am 125 lbs.  The costume is still very big on me. The length is fine (as long as I wear 3 inch heels), but it is very wide and boxy. I plan on using lots of safety pins.

The hat is too small, as many other reviewers said, but I will glue it to a headband and make it work. Overall, it's a good costume for the price.
