This. Comes in many colour combos, including plain black. If you google it you’ll find a discount code too.

Maybe a swimdress with the seam just under the bust?

Miraclesuit . Only way to go. Expensive but if you look after it, rinsing out each wear etc it will last, and they really do work wonders.

I have bought double thickness tummy cover one, the last one m&s but the back comes up to shoulder blades which does look chic.

If your size 12 then nobody is going to notice, unless your wearing a skimpy bikini.
Very few women who have had children have completely flat stomachs.

I bought a swim dress for my holidays last year. Size 14 it covers my fat round tummy.

I'd need a waist high enough to go over my head to hide my sins.

I wear bikinis with a high waist. Cover a multitude of sins. Size 12 too.

I don’t like good or confortable that’s why I asked for suggestions.

M&S have a 20% discount on swimwear at the moment.
They have tummy control swimsuits.

Have you considered a cossie with a control panel in front?

Really, no one cares just wear what’s comfy and you feel good in.

Have I bought size 12 swimwear recently? No. Not for about 30 years.

Do children give a toss what granny wears?
