1. WEAR A SMILE: People are naturally attracted to happy people, so avoid looking rushed, annoyed, or stressed out. A warm smile, but not a big grin, goes a long way to lighten things up. You might start feeling more cheerful yourself!
2. FIX YOUR HAIR AND MAKEUP: Check yourself in the mirror before you leave the house. Since I'm allergic to most makeup, all I can wear is lipstick; so I make sure to keep it freshly applied during the day. Pay special attention to your hair as well.
3. DRESS WELL: It's amazing what a difference a nicer coat or jacket can make. In warmer climates, a pretty blouse or shirt with sleeves looks dressier than a tank top or sleeveless shirt, especially when paired with lightweight slacks or crops instead of shorts.
4. FRAME YOUR FACE: Now that you're smiling, choose simple accessories that you enjoy wearing. Earrings, a nice scarf or necklace, or a pretty pin make a simple outfit a little more attractive. Don't overdo it, though. Think office look rather than party!
5. LIGHTEN YOUR LOAD: Too many bulky packages can not only make you look stressed, but also make you feel that way--because you are! Either bring a tote bag with you to consolidate packages, or take a few minutes to put them in your car before continuing your shopping. If you're shopping at a large mall, it might be a good idea to move your car to the other end for a shorter walk. Sounds crazy, but I do that all the time. Not only does it help my feet, but I also get to sit down for a few minutes in the car.
These tips are from my own experience on both sides of the counter. I learned this years ago when I stopped at a department store one night after work. Since I was still in office clothes, I got noticeably better service that day than ever before. From then on, I've followed these guidelines whenever I shop!
BTW, salespeople get stressed too, especially at this time of year. You can help by being patient, having your cash or credit card ready and being polite. Happy shopping!
