Minimiser bras- do they actually work?

[Sunflowering]

I have just bought a lovely dress that fits perfectly except for being about 1cm too small on the chest. The next size up is too baggy on the rest of me.

Would a minimiser bra help? Can anyone recommend one?

Yes it's going back a lot of years ago but my mum swore by M&S years ago. Hoping someone else has tried them recently to confirm for you.

I think they do but ime lose their good fit after a while; to an extent

Yes, they do, I’ve got mine from M&S over the years and boobs definitely are flatter. Take dress into changing room and get fitted for the right size minimiser bra and I’m sure you will see a difference.
