Grated ass.
So, the other, not unreasonably small pair I put on to try on with a few shirts. They have really unique embroidery on the back, which is why I got them. See?

Yeah, that picture is blurry as fuck. And it will probably disappear at some point, but I have it saved on my hard drive for that eventuality. Oh, and yeah... that chick is totally bowlegged, but whatever.
There's a better view.
So, I'm like, oooh, cute, different, and CHEAP... they went into la cart.
I put them on with a perfectly normal, socially acceptable pair of undergarments.
There's one thing I notice before they go on... there is no lining inside, which is not what I would expect when their is embroidery and metal studs directly over your ass. See?
But hey, what do I know? I lean over to get a pair of shoes to try with them, since they have a weird hem. Surely the designers knew what they were doing when they designed--
OH HOLY MOTHER OF GOD MY ASS
I am going to go out on a limb here and say that most people wearing junior sized clothing are keeping up with the underwear trends of the time.
So, the rear end may be slightly more exposed to the elements of the pants, than say, if one were wearing some more traditional pair of undergarments, like bikinis, or, god forbid, briefs (ugliest underwear EVER).
One might expect that designers of pants would take this into account when designing pants so the e'er valuable ass doesn't rub against metal studs and embroidery when one moves, resulting in pain, shock, and a red angry ass.
But... one would be wrong.
I guess I'm off to find some granny panties.
