...I don't have the dress yet (although I know which one I want). Ordering one that's off-the-peg and shipping is a week tops, so no biggie as I'm aiming to slim down more to size -100 if possible

We didn't order invites yet. We have them chosen though. Most people booked after STDs anyway (we're getting married in Gibraltar, living in UK).
FI has not have a clue where to get his suit from (linen), or anything else for that matter.
I don't have the shoes, or the money to get them (I've got expensive taste, y'know... £160 + dying is a bit out of reach at the mo).
We didn't order the rings (mine is going to be custom-made to fit the engagement ring). FI's one is titanium band that is going to be ordered online.
I'm not sure if I'm just sane or silly. I'm an events planner, so sticking to the first option. Some of the UK brides have their dresses like 8-9 months before the wedding!!!
Anything you haven't done, which other people think you should've had done ages ago...?
