I am trying to find pants that fit now that I am a totally different shape, and I picked up several different styles in 8, 10 and 12. After trying on a bunch, and finding that most of them did not fit, I frustratedly turned to Penny and said "Ugh, I don't know how clothes work."
She raised an eyebrow at me as I zipped up a pair of pants and said "Yes, you do."
I said, "You're right. I don't know how clothes' numbers work."
"Mommy, you forgot how numbers work? I can help you."
And that's why you always bring a Kindergartener with you to try on pants.
