This pattern is from Laughing Moon Mercantile, #113. I did view A (Ribbon Corset). The ribbons are cut on angles, and varying degress so it mocks the curve that normal cuts of several pieces of fabric would do. The fit is pretty spot on. The only thing I don't care for is how far apart the grommets are (I used eyelets). But if you look at the back photos for this they're pretty much the same on the pattern envelope as they are on me. I made the size 8 (26-24-34), although my actual measurments are slightly different from that (the bottom of the corset is not at full hip, it's at the very top of your hips...and unfortunately I have an uber long torso so this sits a little higher up on me than it's supposed to). Basically, just go with your waist measurement. What I love about this pattern is it's so detailed. Every little step, plus inbetween, there are instructions. So much better than the crap that McCall's, Simplicity and all the others put out. It's a very easy corset, all you need to know how to do is sew, measure accurately and be able to install grommets/eyelets, boning and a busk. Those last two were my first try and they came out almost perfect. (I had to readjust the seam allowance for the nubby part of the busk because there was a visible 1/8" space between the front. And the eyelets...well I used the hammer method, so yeah.)
For the fabric I used just a black heavy twill for the inside and the outside is brocade. Too bad they're in small sections because this fabric is gorgeous! (And I rarely use that word.) The ribbons are just your standard stuff, twelve 6.5" lengths of 1/4" featherweight plastic boning, 9" steel busk with a white coating (coating is on inside only) and 6mm eyelets.
