What to check for your routine
Check the combined thickness of your phone and wallet before adding a glasses case. Try the strap range on your body and decide whether the front pocket gives you the access you need.
The edition matters
This guide covers Black smooth calfskin, 10357HFY001; dimensions converted approximately from inches, reference 10357HFY001. The snap belongs to the front pocket; the main closure is listed as a zipper. The M Crossbody has a separate reference and different fastening.
How to choose the best organizer
A very thin divider is a better starting point than a thick insert. Keep the flat pocket usable and avoid filling the narrow body so tightly that the zipper strains.
