To see whether this strap will work for your needs, cut a piece of string or yarn to a length of 42", 44", 46", or 48" (these are the lengths that this strap can be adjusted to). Use this length to wrap around your shoulder or cross body to determine if this length will work with your bag on your body. This strap is 1" wide. Measure the original purse strap that you will be replacing to see if this 1" wide strap is appropriate for your needs.
