Hi ladies,

Just wondered what underwear you are wearing under your dresses, i have a slinky light weight dress so i am unsure what to wear was thinking of getting something like this but was worried about going to the ladies once in it

What about something like this:

Not this one, as it's black, but one that just goes as far as your bust, instead of over your shoulder - I'd be worried about the loo thing too!

Depends if you mind poppers or not? I remember the 'body' fashion phase and I hated them, but for one day they'd be ok.
I'd be wary of the ones that are meant to stay up on their own, I never find they work, but I can't get on with hold-ups either, so maybe it's just me!

Which bits are you wanting to hold in? I would say that you may get a VPL with the M&S one... it depends on your dress
