I cut it to the same size (I thought) as my dress bodice that turned out so nicely. Well, the top was WAY too tight at the waist. I altered the muslin all last light and finally got it to where it felt comfortable but it took many, many alterations. I don't think I like the style enough to continue fussing with it.
That's the beauty of a muslin. You get to find out if the pattern is a dud without wasting your fashion fabric. On to the next. I have shifted gears and will attempt this top (I'll be making the longest version with 3/4 sleeves) out of this vibrant fabric. My husband says it reminds him of a VW van but it makes me happy. He doesn't have to wear it. I think it will be cute with some tapered leg pants in a dark chocolate brown.
The fabric is washed and this time no running dye. I'll soon begin the muslin but first I need to make a couple of fleece hoodies for my daughters, before it gets too warm for them to wear them.
