How to be sexy and plus size

I'm a big girl (size 24ish). I'm pretty confident when it comes to sex and everything and my fiancé loves my body however I do not. It was our 1 years engagement anniversary so I bought so sexy lingerie however the corset fits my body but it has a c cup and I have FF boobs. Yet it's sized 22-24 and the plus size stockings didn't even go past my knees. Now I'm lying on our bed so angry and upset  and feeling hideous. This is more of a rant than a question but why are there no companies out there for us big girls to feel sexy!?!? FYI I eat healthy and exercise
