I realize that the flower details on the bag is only in one part of the bag. If I turn it over or maybe if I'm in rush and there is no any details on it. Maybe I could give it a little details.
Here's a simple restyle. Because my sling bag has a holes on it make it easier to lock the necklace. Find a holes you might want to locked it, if your bag doesn't have a holes or it was a leather / tote / or just doesn't have a holes, you can perforate your bag to lock the necklace, OR you can just glue on it with any details you might want, like a faux flowers, studd. Then adjust the length you want. Once you adjusted it, lock the access so it won't come out, don't tied it too strong in case you want to readjust the length anyway.
