Advice please - underwear for my wedding day, control pants needed!

[beanstalk]

My best attempts at the gym are not shifting my post-baby tummy, and as I am getting married in 2 months time, thinking control pants might be a good idea. My wedding dress is more like an evening dress than structured wedding dress iyswim. What are the best ones for not showing under clothes and that are comfortable all day? I only need something for the tummy, don't want one of those things that come down the thighs too. Some of the ones that come up high over the waist look like they might roll down, do they? And are they a pain when you need to go to the loo (esp as I will be wearing a full length wedding dress too!)
Thanks!

I prefer the waist cincher types that to the pants. I find them more confortable than the pants (particularly for along day) and less faff when you need to go to the toilet. Also they avoid the muffin top look.

Whatever you choose make sure you wear it a few times before the wedding to make sure it is comfortable. Also, I wouldn't buy online without trying on - I found the sizing a bit misleading.

I've got some Spanx, and they are great.
For real control, I'd go for a control body as then they can't roll down, and you only have to navigate the hooks and eyes to go to the loo.

Friend of mine recommended making sure that you leave (or get your bridesmaid to nip in with)a bag with some def non control lacy bits in your hotel bathroom, so that you can nip in there and substitute before your new DH takes your dress off
