Best secret support vest top?

[badgermonkey]

I want a vest top (any colour really) with secret support that I can wear on its own in the summer - just so I can wear a vest without bra straps showing. I'm a size 8 B-cup so the support bit doesn't need to be too strong, but it does need to not show through, IYKWIM. Any ideas? I have very few shops near here so I can't scope out in person, and would like some recs for buying online.

Uniqlo sell them, all colours, have a look at their website. M&S do them too, but I thought their range was terrible.

I bought a couple of black ones from Primark, they have va va voom properties and push the old gals up and at'em

Primark.

I've just bought one from Gap and it's good, although I'm more of a DD cup so I still need additional scaffolding.

Fabric is good quality, fairly longline cut, secret support is secret, neckline comes high enough not to show everything off when you bend forward yet low enough to be a vest. Think it was £4.99 and comes in nice colours (mine is apple green).

Someone else said M&S ones no good. Have just retired a fab, v old Primark one - need to go shopping again.

Bravissimo for real support

Gap ones are brilliant and last really well. I get new ones every year but I've still got some I got on holiday in America 5 years ago
