Is there a place in CM that has a decent selection of halloween costumes?

ALSO,

my roomate and I have been looking for a nice high quality multi-coloured spinning disco ball thingy for a long time now and can't find one (we don't want the cheap little ones they sell everywhere). Any ideas oh where we can get a nice one?

i'm sure the owner of spicy can answer both your questions

There is a large costume store in the city. Problem is I can't remember where it is! There is a small one in Taalat Worrorot that sells those green and pink wigs and stuff like that. If you go inside Chiang Mai Plastics and exit at the rear of the shop, turn right and it's up a little way on the right.
