I was on the fence about Colette's Mabel when it came out last year. I liked the idea, but the modeled photos on the web site just weren't doing it for me. Meg made a couple that I liked, at which time I added the pattern to my mental shopping list. I didn't actually buy it until a couple of weeks ago when it was on sale for $10 at Fabric Mart.
I used a gray ponte with flocked back diamonds that I bought a year ago for $5/yard (also from Fabricmart - I seriously love that site). I sewed the XL according to my current measurements.
It seemed to fit pretty well, but after a few hours' wear it had stretched out significantly. Hate that. The ponte felt like it had pretty good recovery so I figured the skirt was too big, size chart notwithstanding. I took it apart and took in the waistband seams and the top of the skirt seams 5/8" inch for a total decrease of 2.5" around (basically the L size with an XL hip). I tapered the seam to nothing about five inches down. It fits better but still stretches out more than I'd like with wear.
As others have noted, the kick pleat does not behave well in knit fabric. The ponte would not hold a press, so I edge-stitched the outer fold of the pleat. It works but still is not perfect.
The skirt really doesn't need the pleat for purposes of wear but I like the idea of it, or something similar, to give the skirt a little flair. I think I will definitely make another of these*, so I'll have to mull over what to do in back next time.
I did not notice until I uploaded these photos to the blog, that the skirt pulls in front, looking too small. It doesn't feel too small at all, it feels comfy and snug, but maybe I will grade out the next one a little at the widest point of my hip. Or maybe some of this baby weight will come off and I will have to resize :)
*Am I the only one who is always blogging that she will "definitely make another one" but then rarely does it? I should go cut another Mabel right now to avoid making a liar of myself.
