Two part question. please read

I’m wearing this dress to a banquet. I like it but I feel like it’s just a little too conservative for me. I’ll be seeing my husband for the first time in a few months and I want to bring the dress to a tailor to add a hint of sexiness. But what? The only thing I can think of is a little slit or something. Or maybe tighter around the back of the thighs? Or any other ideas or input?

And belt or no belt?
