So I used to work at a fabric store. And you always knew who the dancers were, because they would come in and ask for pink elastic. And we were like "sorry, lady dudes. We've got black, white, and beige sometimes if you are lucky." but I felt their pain.
And then several months ago I was at a (different) fabric store with my mother and I was grumping about how I didn't like the single pre-attached strip of elastic on my leather slippers and wanted to replace it with criss-crossed elastic like my canvas slippers have. And I happened to be standing next to a Dritz (it's a brand of sewing supplies) display board and I looked it over and.... holy crow! It said they made ballet elastic! It said "pink specialty elastic for ballet shoes and slippers". I was THRILLED! But then I looked at the actual item on the rack. And it was beige. Not pink. Not ballet pink. Just... beige.
I thought maybe it was just this store's shipment, or this particular batch, but NO. Everywhere I looked it was BEIGE.
You can buy this Freed elastic or some Bloch elastic in bulk online, but what the razzafrackin' heck would I do with that much pink elastic?
I think the elastic manufacturers of the world are missing out on a sure bet.
