Big size version of this please

[Tummytoomuch]

Went shopping and loved these in all saints today. They go up to a large (size 14). I am 16/18, probably more 18.

Can anyone suggest a bigger version of this?

I feel like I’m stating the obvious but why not buy a slip dress and jumper separately?

I recreate this type of look with a jumper dress (a big like this: www.cosstores.com/en_gbp/women/womenswear/dresses/product.oversized-fit-wool-t-shirt-dress-black.0996204001.html) and midi wraps skirts or slip dresses.
Cos, Arket, Stories are likely to have jumpers that would work
