Dress help please!

[JessyJames]

I need a dress for a birthday party. I really like the style of this one.
I'm 5'10" size 22. I'd like to be in a position to try the dress on before buying it. I've contacted the shop and they don't have a sample of this style in my size. As they're made to order I wouldn't be able to send it back if it didn't fit.
Has anyone seen anything similar from a different supplier please?

That's a lovely print.

I haven't seen anything as nice but I have seen this which is sort of similar.

this from M and S though more casual.

I like the shape of the M&S dress but sadly not the fabric.
I've considered making myself something, but it's quite hard to find patterns and fabric these days.

It's a lovely dress. I really like the style and the fabric.
If you're handy with a needle could you adjust the dress if it doesn't fit properly? (I'm not, so apologies if that's not a sensible suggestion).

Lady V London have something similar They go up to a 22 and can be returned

Slug that's a lovely dress as well. Might order one to see what it's like on.

Paper I could probably alter the dress, but i think if I've spent over £100 it should fit perfectly!
