I normally use shoulder bags, but I need a solution for carrying more stuff to the office and to college at night. Wearing a backpack would make my life easier — I’d rather have my hands free than have to carry an additional tote or wheel something behind me. Besides, I think a backpack would be be better for my back and neck. But I always wind up slinging it over one shoulder with my handbag (which defeats the purpose of a backpack), because it’s a hassle to wear both a shoulder bag and a backpack. The straps get bunched up and it’s harder to access stuff. Do you put your handbag inside the backpack? I don’t like investing in a good designer handbag if it gets hidden away. But I can’t carry my backpack around teh office, so I do need both. Help, please! I need a system that works. Thanks!
