Try on your Halloween costume before the day of a family-friendly party.
Even if you ordered it on-line according to your measurements.
Because the package you received states (in very small print)
“For sizes 2-10.”
Congratulations Halloween stereotype of skimpy/tight costumes for women.
Your power is strong.
* Someone out there actually believes that a size 2 butt and a size 10 butt fit into the same skirt.
** Managed to make it work with a little needle and thread. And the party was mostly outside, so a much-needed jacket helped keep the rating to PG-13.
