Trying a new-to-you trend can be fun, but a little expensive and risky, especially when you’ve had negative feelings about the trend in the past. And sometimes when you love an item in store and know exactly how it will work in your outfits, it doesn’t work out when you road-test it later. In these cases, purchasing the new-to-you trend at a cheaper price is a safe strategy. That way you’ll have tried something new, kept your style evolving, had fun dipping your toes into fashionable trends, AND kept the cost factor low if the item does not work out.
