Alright, so my girlfriend and I are going to do a photoshoot probably tomorrow afternoon/evening of me with my car

She is using my Canon EOS so it'll be quality. I want classy/sexy.
I'm not wearing a bikini, nay nay. But what do y'all think I should wear?
A) Jean skirt, tank top, cowboy boots
B) Tight jeans, cowboy boots, cute top
C) Dress and heels
D) _______________ (insert anything but 'bikini' here)
