Okay, so this is kind of an awkward question...
The dress I got for the basis of my Sloth costume is pretty much perfect, except for the fact that it's a few sizes too big. I'm not exactly an expert sewer, and since the con I want to use it for is a week from today, I don't have the time to experiment on taking it in, because I'll probably end up messing up and having to start over again or completely ruining the dress.
The only reason the size is an issue is in the chest. While many girls find they need to bind their chests to fit male costumes better, I have the opposite issue. The dress looks awkward on me if I don't bulk myself up, but the only issue is that the dress has spaghetti straps, so I don't know how to bulk myself up without using something with straps or without it falling down.
Does anyone have any suggestions?
