I have a narrow knuckle clutch (more of a pill shape than this longer variety) so length wise my phone had no chance of fitting in mine, but the clutch is also very narrow in width. Even if the long style can accommodate a phone, I doubt you’d be able to fit much else. Mine basically only holds one lipstick, gum, and cards.
The interior structure is actually much smaller than the exterior appears.
I’d also keep in mind that the heavy embellishment may create snags in any clothing you wear with it. My clutch features heavy beading and embellishment and, while stunning, I’ve found it to be very impractical. I’ve already damaged a nice pair of trousers and a skirt that I’ve worn with the clutch, despite being hyper aware of not brushing the clutch on the fabric.
It’s an exquisite piece but very fussy!
