That dress is a bit much, I’m your age and I’d not wear it, my daughter in her twenties wouldn’t wear it either, it’s really tacky looking sorry op. I. Surprised it costs as much as it does. It looks like a sparkly negligee.
why not go sexy but elegant, a pair of nice wide leg trousers, say in cream wool, a silk sleeveless shell top or cami in a nude colour or contrast like navy or bronze. There are many ways to dress up,look sexy if that’s what you’re going for, and I assume it is, with that dress choice, without wearing completely transparent clothing with sequins stuck on.
