New to Balenciaga

Maybe the Part Time. Discontinued "Purse," was specifically meant to do that. The Day is a single handled shoulder bag (My favorite). Follow HMWE's suggestion, and have fun investigating. :yes:
 
If you want something Big than I would suggest either the Work or the Weekender, depending on just how big you would like your bag to be. You might try the Part-time as well, but it's smaller than both. The City will be too small and the Day only has one handles.
