i need help please

so my bf told me to wear something nice tomorrow night because he made dinner reservations. it was supposed to be a surprise but i needed to know lol. i told him how nice to dress like on a scale of 1-10 and he said 7.

im a very fancy/ classy person. i love dressing up. but i dont want to overdo it ya know. i asked him jeans and heels or a dress and he said either works.

what do you guys think? im already stressing out😂😂😂😂
