My sister just got engaged!! I wasn't allowed to be involved with the other two, but this one and I are good friends I really want to organise something for her, not necessarily a shower - which will definitely come a bit later, once they start organising everything - but something for her and I, and maybe a few of her friends.

I just texted her and asked if she wanted to go on a wedding dress date soon, go and try on big, expensive dresses with no intention of buying them, just to get her in the 'princess' mood. Any other ideas?
