520 hp overs Started by: mrsdminor21

I’m due to have 520 hp overs in July and have a wedding 2 weeks later, I have found a dress I want to wear but unsure what size I would need I’m currently an empty 34b and wear a size 12 and can fit into size 10 and 12 dresses so what size should I get? It’s quite fitted but thick straps to hide the supportive bra thanks xx
