i really like the femme doctor costumes i've seen on LJ - they're really pretty and interesting. that said, i know that when i dress as five it will be in trousers (and was when i was eight and ten and.... ainley). i guess i have been indoctrinated too well. also, i don't know - there's a bit of me that thinks it'd genuinely be beyond me to re-think the costume and then present it convincingly. the rethought costumes are more than just substituting trousers for a skirt, or they should be. and if they aren't, then perhaps you should just be wearing trousers.
