I am very unfamiliar with using muslins, but I have found that I need to with fitting my daughter, as she has a full bust, but wears a size 6 in RTW. I bought a size 14 pattern for her new vintage halter dress (picture Marilyn Monroe’s white one), going by the high bust measurement and the waist size, as it is very fitted there, too.
I’ve basted the muslin and there was gapping at the upper side of the armhole (actually, the side of the halter piece). I pulled in a dart there and pinned it. It is about a 45 degree angle. It now looks like perfect fit on the muslin. What is the best way to translate this before I cut out the fashion fabric? If I cut the fabric in the flat shape that this now represents, will that work? OR do I need to mark the dart and cut out the fabric and do the actual dart in IT? It’s a pale background with an irregular print that I don’t think would be noticeable with a dart sewn in it. I have it pinned so that it still makes a nice smooth line under the arm and it is on grain.
Any help/suggestions would be appreciated. She is so looking forward to this dress and I want it to be really wearable.
