Red formal work outfit needed - help please

[Custardapples]

Hi - Size 16, big bust, hourglass shape. I need a formal outfit for a work event. Not a cocktail dress but very smart. I will be working the event all day hosting clients and contacts (12 hours) so I need to be comfortable for the whole day. I have some red shoes already (cherry/bright red) which will be perfect so I’m thinking red or something that goes with those for the outfit - either a dress or a red top I can pair with formal trousers.
It’s midsummer so could be hot and the event is inside (air conditioned) and outside so need to be able to move between the two! Need to be able to sit comfortably and not show too much skin as its work.

Any ideas? Thank you!

Budget?
How curvy do you feel comfortable with?

I'd look at wrap or sash dresses. Do you want sleeves?

Thank you. Happy to look at anything. Ideal budget up to £70 but I’d go a tiny bit higher if I thought it was the right thing. Would like to spend less if I can.

I’d get a red silk or satin shirt and pair with your shoes and formal black trousers - assuming you have some

ypu’ll be able to wear it again and again.

Or black and red

Oh my goodness - this is gorgeous. Hopefully I would fit in a 14 as it runs large.

Love this idea.

Would you use Vinted,? there are lots of red dresses on the website.
