Pro's: It's a beautiful bag to buy!
Con's: It's white : ) It can be very hard to keep looking like new. I guess as long as you know it will show the dirt, especially the lacings on the handles, and you know that there can be dye transfer from clothing, and you are comfortable with that, then go for it : ) Apple Garde can help, but I don't think that Apple Garde can totally protect.
I love the look of white/ off white/ ivory balenciagas, but the maintenance and worrying about getting it dirty are too much for me to own one!
I wish you well,
Bridget
