I have a wrap front dress for a wedding this week and the dress does fit me however, having just tried it on, the front is bothering me and needs to be more secure, I'll be bothered about flashing all day! It feels like it just needs sticking in place. Or is there some kind of underwear/lace thing I can wear under it? I really can't spend money or time/stress looking at another dress when this one just needs holding in place or making more decent. I'm stressing! Any ideas for something that can go underneath it or something that can hold in place?
