I cut out the underlining (in heavy white suiting), had my cousin come for a fitting, then I cut out the sequinned fabric and the lining and slapped it together. I used French seams to make the casings for the plastic boning. Here's where I'm going to give away one of my trade secrets. I never never never buy plastic boning from the fabric stores. Not the covered or the uncovered kinds. Instead I go to the hardware stand at the flea market and buy extra long zip ties. The longest I can find. For this I used 1/4" zip ties, but the other widths work for other applications. They are just a thick as the plastic boning and about 1/10th the price. I paid $1.00 for a package of about 20, at 18" long. So cheap! The secrets out! If you have ever commissioned anything from me that is lightly boned (plastic, steel is a whole different story) it was made with zip ties. I feel so much better getting that off my chest.
I hope you are finding this information useful, I'm really not trying to create a tutorial, I just wanted to share how I did it. If you have any questions about what or how I did something please don't hesitate to send me a message or leave a comment. Be sure to check out my other blogs about this costume: the overview and how I made the undershirt. There's also lots of resources on my Elsa Board on Pinterest.
