Wouldn't it be a waste of sales space.
I know nothing about dance wear but I'm sure you have more chance of selling 3 or 4 leotard Pineapple things than 3 or 4 pairs of bags and a circle skirt.
I'm not getting into what people should wear as each to there own, but in a shop where space is money I thought you would be better of selling stuff there is a bigger market for.
Maybe sell your bags and tshirts on ebay, we all know there is a market for northern soul on there..
Is there a passing trade for bags where you live?
(Just a thought)
