Trouser suit for older woman wedding guest?

[WouldBeGood]

Can anyone help? The brief I got was “three piece with a camisole”

Up to £500

Karen Millen?

How old? I have the same request from my Mum but at 84 I doubt Karen Millen would suit her!

I was thinking of something more forgiving, drapey jacket, flowy trousers, but drawing a blank so far

70 something- a friend’s mum

Don't now if this link is any good. Its a photo of the queen in a trouser suit and she looks really nice

Thank you @waltzingparrot , that's the kind of thing I meant!

Oh come on people, a wedding, a £500 budget and you're asking what the Queen would wear?

I'm absolutely shit at wedding dressing as I've been to one in about 20 years but I'd start with The Outnet.
Then I'd move on to Me and Em
Massimo Dutti
Arket
Cos
The Fold (some of it's a bit corporate but not all)
Winser as suggested upthread.
maybe Whistles and &Other Stories (I don't like their quality but for a special occasion....)

And I'd visit somewhere with a good range of independent shops.

Assuming there's time, I'd also wait a couple more weeks while more new stock comes in.

My mum wore a trouser suit to my wedding (she’s never been keen on dresses), and she looked wonderful! I think it was from Jaeger as it was back then. A silk satin trouser suit would look great. Maybe have a look on Etsy?

Three piece? Does she mean with a waistcoat?

With a camisole thing, I think.

Thanks for the suggestions!

Thanks @pinkcadillac, that looks spot on I think!
