First, if you haven't already heard of it elsewhere, Yasmine Surovec from the brilliant A Print a Day blog has a new magazine especially for crafters called Parasol Craft. It's only 2.50 USD, and full of gorgeous things, interviews with artists and pictures of the beautiful things they create, it also comes with some things for scrapbooking, a darling doll project, instructions for creating and using Illustrator brushes with vector files to practice with, and some really lovely embroidery designs. 111 pages of goodness.
Rachel at Instructables has great step by step instructions for making your own panties and bra. Since you make the pattern by using one you have that you kind of like the fit of, you can adjust the fit to be perfect, and unlike some bra projects I've seen on the net, it WILL work for something more than a B cup. Oh how we envy you ladies with the high and perkys! (perkies?)(Umm.. *blushes and waves to the guy in Canada and the guy in Japan* you can ignore that whole last paragraph!)
If you can draft patterns, The Canton of Gleann nam Feòrag Dhuibhe has instructions for making all sorts of garb.
I reposted my pirate eye patch pattern here
This bat mask is a costume all in itself with a gorgeous little black dress. For this? I'd start wearing contact lenses again.
If you are more the Winter Queen type, check out this necklace.
