Stitch with Style is a special fashion sewing edition of Stitch Magazine, out on newsstands May 14th. (You can find ordering info and stuff here.) The magazine features the dress and instructions, and then you can download the free pattern on their website to make it yourself! Update: you can also buy a digital copy of the magazine here.
The dress made its merry way to back to me yesterday, along with a fresh-off-the-presses copy of the magazine.
The fabric was a delightful find at B&J Fabrics. (I don't see this particular fabric on their website, but I think they have more, so you could call them or email them this picture if you're interested in buying some.) It's a pure silk organza with a soutache-like ribbon embroidered on top. I choose a periwinkle silk habotai as a lining/underlining (there's both in the bodice) to set off the deep blue of the ribbon work.
I'm definitely going to be making this design for myself now that it's available to download in a range of sizes (XS to XL, or bust size 32" to 44-1/2"). More to come on that!
