Recommendations for a flattering summer holiday dress in size 18

[Hogett]

Hello!
I am looking for a nice summer dress to take on holiday with me, south of France at end of August, mainly to wear for meals out etc. Im 5ft 8ins and a size 18

So far ive tried a spotty A&F dress that made me look huge, a fit amd flare dress from Monsoon, who's zip wouldnt come past the skirt and top join ( tried 3 of these) and now I need some input, as im at a loss.
Nothing to expensive,suitable for warm evenings, have to usually shop online as nearest city is a few hours away and although we have Next all 14+ sizes vanish quickly.
Open to most styles, but if it hides my stomach all the better, open to colours, prints etc.
Thanks

I’d only look at linen, cotton or maybe viscose
Sainsbury’s actually have some nice maxi dresses atm

I have this dress, it's so flattering and has pockets!

I bought this the other day and it's great, really hides the apple belly!

HUSH Air Flow Stripe Maxi Dress containing LENZING™ ECOVERO™ Viscose, Purple
A bit ££ but on offer
Also the straps are adjustable which I love

I've just bought this dress for my holiday, https://www.albaray.co.uk/products/painterly-palm-maxi-dress-ss26

It's really lovely.

I've got about three dresses from this company, fantastic quality and very well cut

This is very flattering, watch the video

@Idontjetwashthefucker @Tulipvase how long is it on you please? The description says a Regular length is 128cm which seems way too short.

Well I’m approx 5 ft 1 and it’s just above ankle length on me. Not tripping over length but not midi (on me) either.

I’ve got a couple of kaffe teeshirt dresses in size 18. Well made roomy ( don’t cling) comfortable plain but stylish snd good value for money .
