Is bag more important in women's fashion than shoes
You need a purse …just one nice black or brown leather one. That'll do. Maybe a summer and a winter one if you have seasons. They should last years if you avoid trends and choose a classic style. Replace when necessary. But wear cheap shoes and any hope of looking good disappear.
Wear your Levi's with a white T shirt and a well made pair of boots and you will look good…wear with flip flops (anywhere BUT the beach) and you can look like something the cat dragged in. Wear well made shoes that fit you properly and you will carry yourself in a manner that shows you take care of yourself and spend your money on things that count. Quality footwear matters, not purses.
