Those wedding dresses are rough, they all look like underwear to me. I'm surprised she's not getting married in one of her usual loungewear tracksuits (she'll probably change into that in the evening!)
One of my friends got her wedding dress from a place near where Stacey lives, which could well be where she's getting hers from (they are exactly the sort of place that would give stuff away to beggy instagrammers) I had to go there to for my bridesmaid dress fitting. They were bloody useless, and despite us all going for 2 fittings (my friend the bride had about 4) none of our dresses fitted properly, mine was too big (they insisted on ordering it in a 22 despite the fact I was a 14 at the time, and then said they couldn't take it in!), my other friends was about a foot too long and the brides didn't fit properly either and we had to keep lacing her back into it throughout the day. Based on that if Stacey's dress comes from there it will be bloody awful!
I reckon she has to keep all the stuff in her bedroom because Mandy is downstairs looking after the kids/ doing the cleaning.
