I'm getting married in May. Not gone for a traditional wedding dress - I'm wearing a fairly floaty dress with spaghetti straps from Whistles that has zero support. I am small chested - 36A - so don't need a ton of support, just something to make it look like I've not gone bra-less, and give me a bit of shape. It's years since I've owned a strapless bra and that one was pretty uncomfortable. What would you recommend?
