Thinner layers should help. Or alternatively consider reheating the ends after you are done. You could point a heat gun at the end of the bracelet where it delaminated until it remelts and smooths out to keep it from catching a layer on some clothing.
Or you could dip the ends in boiling hot water for 20 seconds then pull it out and smooth it with something smooth and hard like a counter top or the hot glass of a UM2 set to 80C.
I'm guessing that the issue is more about the surface not being smooth enough such that it catches in clothing. You should ask them to take a photo with a cell phone and text it. Cell phones tend to be very good at macro photography.
What is the nozzle diameter on your printer? I'd make sure that the layer height is smaller in proportion to the nozzle diameter, so that the plastic is spread onto the layer below, rather than being dropped onto it. Perhaps printing hotter would help - 0.3mm layers at 60mm/s is quite a high volume per second - perhaps the plastic is not heating fully before it is extruded, further reducing the adhesion between layers?
But, it will be easier to tell whats going on when you have pictures. :-)
