Just throwing ideas around. I keep thinking of random things that I want but can't find anywhere:
-iridescent green/ violet mascara with dramatic color shifting properties $20-$30
-black, non-wet-looking lipstick with blue-violet iridescence $15-$30
-an Amulet of Akatosh as seen in Skyrim made to be an exact replica of that in the game, preferably in a grey metal $30-$50
-heels with clear resin platforms and with crystals suspended inside $$$
-jewelry incorporating aerogel $$-$$$
-a belt that looks like one long metallic spinal column with a pointed end $$$
-anything that looks as awesome as this dress, although I have doubts of my being able to afford this one:

I salute your prowess if you attempt to make any of these.
