Hi Ladies, this longtime Bal lover is thinking of taking the GD plunge. My local retailer here seems to only carry the styles that don't have zip tops. I believe they have the 24 and 36 hour styles. They have some lovely colors and I've come so close to buying, but just haven't because I'm a lover of zip tops. I'm terrified that my things will fall out while I'm wrangling my little one, going through airport security, etc......I can try to zip my wallet in the inside pocket (not sure if it's too big though as it's a Balenciaga mini compagnon and it might be a bit too large to zip into the inside pocket). Those who have these bags, do you think I'll totally regret getting one because of this???
