When shopping at a consignment store, high-end, designer clothes can be purchased for a fraction of their original price. Another bonus? Buying secondhand clothes at thrift stores or consignment shops isn't just good on the wallet, it is also significantly more efficient than buying new. The amount of energy used to make new clothes is much lower than the energy used to resell them. One tip: When you find tailored pieces, like pants or jackets, that fit you perfectly, ask the store to hold items from that seller. The next time he or she brings in clothes, they should fit well, too.
