Strapless bra for larger chest sizes?

[Lovingsummerflowers]

Has anyone come across a good strapless bra for wearing under strappy summer dresses etx, suitable for 32E chest size? I have one from years ago but it slips down all the time so looking for an alternative. Thank you!

I bought one in that size from Primark recently. Does the job nicely & relatively cheap.

I have never come across a comfortable strapless bra - the band always needs to be tight as that is what holds everything up. So I'm reluctant to spend £££ on one.
