Oh man, that's tough. My first instinct was CHANEL! but then I thought about it for two seconds and realized that you have the rest of your life to wear Chanel, you can buy it next year or in 40 years and it will be the same. old ladies look classy in Chanel. But old ladies look much less classy in sexy, high LV heels.
So I say LV bag and shoes, or maybe Chanel sunglasses and shoes (*gasp* no bag? well.......)?
Good luck with the big decision.
