Wedding outfit- what are these all in one thingies called?

[LovelyBrewandBiscuits]

I've just received a wedding invite. I know what kind of outfit I want but I can't find it because I don't know what it's called and I don't know where to look. Help!

I want one of those all in one thingies with trousers attached to a sleek top. Like this but obviously not this this

What are these called? And where do you think I could get one? What colour should I go for?

What do you think of these? Would I be making a massive mistake getting one for a wedding?

I'm 30 years old, 5'5, size 8, quite big boobs...

Any help much appreciated

They are called jumpsuits and I saw a lovely smart navy one in next the other day that i would brighten up with accessories etc.

Thanks folks. I did think Jumpsuits but my mum always used to call my dad's overalls a jumpsuit so I didn't think that was right.

Where did you guys get yours from, please?

Oh, New Look would be great actually coz I don't want to spend much
