Can anybody recommend a decent multiway / strapless bra for bigger girls ?

Hi
I usually only wear bravissimo and Freya 34g and I looking for a bra I can get away with on holidays with strapless or more skimpy sundresses ?
Ideally I'd like clear straps that I can attach so I still have that support ?
Would appreciate any recommendations pls x

Curvy Kate have a fab range and their strapless bra is excellent!
