That’s lovely OP, hmm bra wise it’s a bit tricky I don’t know if they still do them, but you used to be able to get ones that sort of had straps criss crossed round your lower back, rather than the normal back on a strapless bra.
Shoes lots would go with it, depends what you like pretty sparkly high heel sandals would look good, or a block heel, pretty flats.
I would go for heels though, as I love heels.
