Rat Queen completed

The costume is mostly finished; I just need to finish a few accessories (tights and gloves). 

Let's go through it piece by piece:

The Corset

This corset is made from pillowcase material and cotton sateen. It is definitely not designed for tight lacing. I used katafalk's tutorial to draft the pattern. This is the first time I've used a busk in a corset. Busks are a bit tricky to insert, but make it a lot easier to put the corset on. I used Bishonenrancher's video tutorials as a guide, and ended up with a piece like this:

I then sewed the fashion layer and strength layer. Note that I flatlined the grey cloth to a stiffer cloth before I started sewing all the pieces together.

Here's the corset with all the pieces sewn together. I think if I make this corset again I'll make the back lower.

The corset on my dress form. You can see here that I sewed in the boning channels, adding the plastic bones, then sewed on bias tape to finish the raw edges. Once that was done I added grommets to the back.

This is the basic corset finished: the front

the side

and the back. I added a modesty panel to hide the gap.

The next step was to decorate the corset. Emilie's corset is covered with rhinestones, chains, beads, sequins, and charms. I bought a bunch of these from ebay and glued them on with E6000. I began by sticking on the larger gems in a regular pattern, and using the smaller gems to fill in the gaps. Once that was done I sewed on the chains with embroidery thread, and added the key charm to the chains with jump rings.

Here's the finished corset, with the modesty panel attached. I think adding the embellishments was my favourite part of making this corset.

I still have a ton of gems left over, so I'll probably make some gem encrusted accessories to sell in my etsy shop and at Malta Expo.

The Wig
I didn't end up dying a wig after all. My friend wants me to play Fionna (Adventure Time) in a skit, and I need a long blonde wig (we're doing Good Little Girl/Bad Little Boy). I bought a wig from cosertstudio on ebay.uk

Coserstudio is a really nice seller. They asked me whether my item had arrived on time, and were generally very helpful and polite. The wig did arrive a little bit late, but only by a few days. I always order wigs in advance so that I don't have a panic before the convention.
The wig is a little bit shiny, but it fits well, and the colour is perfect. I might curl the ends slightly, but overall the wig is just right for this costume.

Bra

I bought this bra from ebay. It's exactly what I need, and has great details like the stitch lines and the black lace. I sewed in some padding in the cups for modesty, and glued on the gems with E6000 glue. And that's how you make a sparkly bra.
