uh ok! lol. Black suit def!! maybe get a shirt the color of her dress. like going to the prom or something. Just not to fancy!! tie? um, lighter blue? i don’t know!
good luck with your girfriend! aww!

go with a navy blue suit, a pale blue tie and a either white or light lightb blue shirt underneith

just anything i am sure you will look great on anything ) just be urself dont worry too much about what u r going to wear and i recommend u that u wear what ur gf bought u cuz after all she bought it for u

the suit should be black with a dark blue tie then with some nice new shoes dat well look awesome

I would try to match your tie to her dress. Try and get only colors that she will be wearing so when people see you two together its like “Aww look at them they match, theyre so cute”. Then she will feel like you put in the extra effort to match her to make the night look even better.
