It's tough to establish a unique style if you're wearing the same clothes as the person sitting next to you. Having your own style means standing out from the crowd a bit. So how do you do this? If you want to shop the stores, you're limited to what's within driving distance. But with online shopping, your shopping borders are boundless. And many online stores even offer free returns.
If you'd rather shop around town than online, stick with the smaller boutiques or even vintage and consignment shops. You can find some really good deals and feel secure knowing you're buying something that nobody else is likely to have. Just that in itself will help you to establish a unique style. If you're really lucky, you'll find one great piece and several accessories you can use as the building blocks for your look. For example, there's nothing wrong with wearing the same plain white tee everyone else has, if you accompany it with a great vintage cardigan and fun brooch from a local boutique.
