Hi,
Well I haven't had this experience. However, I have not carried her much. I would be curious to know how often the bag is being carried. I asked because it is not meant to be carried everyday.
As to the sequins it is sewn in rather well. I would say it bends easily but it would take a mishap for it to just be falling off. Like a SJP robbery kinda mishap. I owned the previous version in gold. I wore it crossbody which was not the intended and the crystals fell off having rubbed against my body. I really would be very surprised that the sequins is dropping off though!
