It's your super special day and as well as looking stunning in your dress you don't want to freak out your husband to be by wearing hideous granny pants! This will give you tons of slimming power but will almost allow you to breathe, eat, drink and dance. However, debenhams do an amazing version - they go up under your boobs and down your thighs, but they are really smooth and seamless and comfy, with no fat hanging over anywhere either. Combining firm compression with stay-in-place benefits, this style has adjustable straps and full coverage throughout the torso, hips, butt and thighs. They do lots of variations though and you can get ones with legs/shorts or ones that are like knickers at the bottom so you can wear them with trousers etc.

Its open-bust design means it has straps for stay-in-place power while allowing you to wear your preferred bra.I second Sammy85's comment - I have a pair of good quality (Trinny and Susannah endorsed ) suck-you-in pants of the under the bust to knee variety.

Instead of a bodysuit, go for high waisted briefs such as the Spanx Higher Power High Waisted Shaping Briefs or body shapers such as the Spanx Higher Power High Waisted Shaping Shorts.Ideally, shapewear shouldn't roll down or limit your circulation — you should be able to breathe, sit and eat comfortably! We recommend that you go for shapewear in a natural or pinky colour as this will blend in the best – even if your dress is white.

Note: I am also size 10-12 - being size 10 doesn't necessarily mean you have an amazing figure - it depends on where you carry the weight, and how tall you are, to a certain extent!The SKIMS brand is a staple for both Messiah and O'Connor along with GH editors who love the color and size ranges.
