Every woman needs a long-sleeved little black dress. It's that kind of dress that can go a long way--from coffee to cocktails, casual get-togethers or formal events. No matter how many times you repeat it, people might not even notice you wore it again. It's a trick of styling it differently. Also wash it with a perfumed fabric softener to keep it looking brand new. Try Downy Parfum Collection. The Happiness variant is made with a scent switcher technology that gives different scent experience with every rub. So if you're running from day to night with board to bar meetings, change the aura and aroma of your dress with Happiness. It's an instant switch! Photo from Getty Images.
