Hey - I need some advice. I have my fitting this weekend (at David's) and I haven't actually bought my bra/slip that I plan on wearing yet. I had thought I'd just buy them there when I went in, but I've been reading a few things online that make it sound like it might be problematic. Should I try to buy them before hand? I'm just a little skeptical about buying the slip without having the dress because I know slip fullness can effect the length of the dress. Does anyone have any experience with this? Thoughts?
