The corset dress is everywhere!
The strapless or spaghetti-strap dress with corset/bustier/bra top shaping in the bodice, in cute cottony prints, rocked particularly often by Taylor Swift. Seriously, I've seen her in them in like four magazines. Here's just one example of her in a cute grey Rebecca Taylor corset dress:
Taylor also wore the pink version of the $495 Rebecca Taylor while shopping at Anthropologie in NYC:
It's a super fun style, but there are pretty much no patterns readily available that I've found (let me know if you know of one!). I thought about using a bra pattern and drafting a bodice/midriff to add to it, but I also considered just seriously altering this 90's-ey Vogue special occasion pattern, Vogue 8288--I ended up just using the top 1/4 of it and giving it a natural waist and a waistband, and a gathered skirt.
So fun and summery!
