I have a coach purse and it's straps keep on falling off my shoulder. It falls off almost immediately. I love the purse and i dont want to return it and i dont like the messenger bags :/ i know you can hold onto the strap but i dont want to do that all the time and if i have soemthing to hold, i can't keep on holding onto the purse strap. i really dont know what to do now, i just love this purse!! any help would be really appreciated.
