Want to do something sexy

I feel very insucure with my body for starters and I have a chubby stomach and big thighs and a big ass and small boobs. I want to wear some sexy lingerie for my husband or something sexy but I want to feel comfortable and sexy at the same time. He doesn’t really like lingerie but I feel like it would make me feel sexy and more confident so what should I wear to get him going and myself confident. Should I just go to Victoria’s Secret and see what I like before going somewhere cheaper to buy something?
