Thank you ladies, your inputs are so helpful!
Actually I just got a email reply back by balenciaga.com, they told me that they will restock in couple of weeks, and also they are going to have new color Citys with planets/boobies!!!! How exciting!!!!
And CandyJanney, I found the boobies are so useful that they can increase the city's strap so that you can easily carry it accross your body. Plus, if you just simply hang it on the side of the purse, when you walk or run with it, the boodie will jumping around, and its just too cute to miss.....
Oh wander btw, do you still remember where that thread talking about how people use their boodies? Wanna go check it out!
