Hi everyone. I’ve recently purchased a Bella and really in love with it. However I’ve a huge complaint about the bag closure - the straps would literally loosen up in a few steps once I start walking around. I couldn’t find a way to close it tightly and my SA only suggested me to tie a knot on each side. I tried it but found it looking really terrible and difficult to open with one hand. Does anyone have any solutions to it? Thanks!
