[dontwanttogetoutofbed]

i could go out to buy an item or two tomorrow, but only at the high street.
The party is tomorrow eve.....

Cowboy/cowgirl? Jeans & checked shirts - but you'd need to get hats...

James Bond & a Bond girl? - smartest suit for him, flashiest dress for you...

Depends what sort of things you have in your wardrobe!
