The only things I know for sure about culottes is that, one, I've yet to see them be flattering on anyone, and two, you will be asked about the "skirt" you are wearing about 10,000 times throughout the day. Let me take this chance to remind everyone that culottes are, in fact, pants.
They are, however, comfortable and wind is able to get all up in there if you're looking for some ventilation. But (and I can't stress this enough) so very unflattering.
If you aren't getting a "middle school art teacher in a classroom with no air conditioning on a 90 degree day" vibe from this post, something is wrong with you.
(Not that there's anything wrong with being a middle school art teacher.)
