I'm completely new to Balenciaga and have no idea what anything is. I saw a Bbag today at a resale shop and really liked it, but have no idea what style it was. They all look the same to me! What is the best way to learn? Is there anywhere I can go to look at all the bags side by side for a size comparison? Or find the measurements of the bags? Also, how do you tell the difference in years? Is it solely based on color? The bag I saw today was a pinkish color. Any ideas what color it might have been? TIA!
