I'm so disappointed! I just finished BWOF 07-2008-131 (the pants to match the BWOF 07/2008-133) blouse and they are too small – embarrassingly so! I don't know what went wrong. I used the same size I always use. I checked that I traced the correct size. I made the same pattern adjustments I always make (length adjustments). I haven't gained any weight. I followed the fabric recommendations. I just don't understand what went wrong. (whine whine whine) I'm especially disappointed because I did some of my best sewing on these pants. I remembered to interface the fly front zipper area. I even remembered to use stay tape on the hip yoke pockets.
Here's my theory. In the US, size measurements are not standardized. If you have a size 12 in the Gap, for instance, it may not be the same as a size 12 in Anne Klein. This is probably even more true with larger sizes. Maybe the size measurements in Germany are not standardized, either. Maybe BWOF copies designers samples exactly and therefore copies the differences in size measurements. Sallie Sahne is a designer that often appears in BWOF's plus collections. I've never had this problem with Sallie Sahne designs. The blouse from this collection (from Delmond) is a little tight and that further supports my theory.
Yes, I know this would not have happened if I'd made a muslin or took flat pattern measurements before sewing. Even after this fiasco, I hate making muslins, but I can learn to take flat pattern measurements before I start tracing.
