What dress style suits a short frame for a casual July wedding?

[Fidgety31]

I never have the need to wear dresses so looking for advice for a summer July wedding . Not posh… register office and casual type reception .
Normally dress very casual , jeans and jumper etc .

Body type - 5ft3 - short legs with fat knees so above knee isn’t ideal . Flat chested . Back must be covered due to neck bump. Flabby belly so nothing that clings .
clothes size -12-14
Skin colour is pale with ginger hair . Age 50s.

Happy with any sleeve length. No tiers or flappy or volumous clothes as they don’t suit my short frame .
Happy with any footwear.
Also any colour .

Probably will never wear again so max budget would be around £100.

Any ideas gratefully received !
thanks

Jumpsuit?

Something like this?

The problem with this season’s dresses is that they are voluminous. I’m also 5’3” and am looking at petite dresses these days.

A Seasalt dress that’s a bit more casual.

@Overtheatlantic they are so frumpy in my opinion

Put that into Chap GTP op see what that comes up with?

The second one is fairly frumpy but I think the first one could look nice with fresh hair and a bit of jewellery. PP mentioned a jumpsuit but I would steer clear of jumpsuits in your 50s if you have an active bladder.

It's a bit difficult to judge how dressed up you're aiming for, but here are a few options that, although they aren't fantastically dressy are (I think) different enough from bog standard midi dresses if it's a relaxed do and you just want to be a bit smarter than normal.

Gingham wrap dress (dammit, just seen that it's slightly below collar-height at the back - maybe not).
Green linen mix. No flappy bits and the slightly gathered effect might camouflage your belly.
Simple red dress with ruched top (petite) - this would be easy to wear, unless you think the ruching makes it too much like a sundress or object to the glorious red with your hair colour. Probably more money than you need to spend though.

Do any of them seem the right level of dressiness and a style you'd feel comfortable wearing?

One of these?

Thank you for the suggestions … going to have a look at each one now

Look on Vinted if you won’t wear it again.
