Is buying clothes online an easy alternative then going to the mall? I find though a Retailer's point of view that the answer is yes. If you shop smart. You have to look for a few things: Quality, Price, Return Policy, Security, Shipping & Handling costs and best of all and a very important one, Customer Service.
Quality is hard to see on screen but most retailers who carry Designer labels are picky about the quality.
Price, check with amazon.com, eBay and the search engines for comparison prices.
Return Policy, 30 day minimum, flexible with size exchanges.
Security, I suggest a prepay visa or a secured charge card with theft coverage.
Shipping & Handling costs, look for minimal cost per garment and take advantage of free shipping when shopping during holiday seasons.
