Three piece suit for DDs prom

[Helpmechooseausername]

My daughter really wants to wear a three piece suit (jacket, waistcoat and trousers) to her prom. She really likes this Suit but my budget just can't stretch to £150, although I do acknowledge that is not that expensive for what it is. I've gone through vinted and eBay with no joy. Anyone know where I can get something similar? Thanks

My niece mix and matched different items to get a 3 piece suit for prom. She had:
Zeco Schoolwear Zeco Girls School Fitted Eco Blazer in Navy | Childsplay Clothing
A pair of navy school trousers in the same shade
And a navy waistcoat she found on vinted. It didn't look like a school uniform at all (the blazer was cut really nicely)

Thanks. I think I might end up doing a mix and match.

I should have said, she's 16 and taller than me! Wears a women's size 12/14.

The age 18 or age 20 might fit her in that blazer x

Would something like this work. That’s a lovely suit she has chosen!

There are Zeco trousers on the same website.

Thanks, but it really needs to have a jacket. I think I'll probably have to get a cheap ish two piece suit and get a waistcoat separately. Thanks though

Thanks, but she's spent years in school trousers so wants something a bit more dressy for her prom!

Does it have to be navy? Dd wears suits to her school formals, and we get them from Disturbia. You can mix and match the blazers, trousers and waistcoats. They are mostly black though.

Oh she loves the disturbia website! She's got a few things from there already, and I've looked for suits on there too, but nothing suitable.
No, doesn't have to be navy. Just a proper suit!
Thanks
