A lifetime ago when I (barely) made a living selling women's clothing in retail stores I became pretty good at judging which customers were the most likely to return the clothes they bought. A good indicator of whether or not the customer would keep the clothes she bought was how she dressed for her shopping excursion. Dressing for shopping success can save time in the dressing room and prevent you from having to return fashion pieces that don't work.
One of the keys to dressing for shopping success is to think about the types of clothing you are shopping for and dress accordingly. Wearing the right undergarments is crucial to judging the fit of a garment. If you are shopping for an evening dress for example, then you need to wear the same strapless, padded or plunging bra that you are going to wear with that evening dress. If you aren't sure what kind of evening dress you are going to end up with you can buy a convertible bra that allows you to arrange the bra straps in different ways or a bra with removable straps that can convert into a strapless bra if needed. If you intend to wear shapers to slim you down and smooth things over in your new outfit, be sure to bring the shaper with you or simply wear it while shopping.
One of the worst undergarments for shopping include sports bras which flatten your chest and give an inaccurate idea of how a garment will fit and hang from the chest area. Brightly colored or patterned lingerie that shows through garments is distracting. A T-shirt bra that blends in with your skin tone and seamless panties that give the illusion of not wearing any panties are more discreet and versatile.
What you wear shopping should never distract from the things you are shopping for. If you are shopping for a cute top, then wear bottoms in a neutral color. Trying on patterned or brightly colored tops with pants in a clashing color or pattern creates looks chaotic and makes it harder to judge if the top is working or not.
Shopping for clothes generally involves a lot of dressing and undressing. It sounds fun and sexy but the wrong clothes and accessories can make shopping a real hassle. Long necklaces that have to be removed every time you try on a top or dress, bracelets too big to allow narrow sleeved shirts to be tried on and big earrings that threaten to get caught in any garment you have to pull over your head, and rings and bracelets with prongs that snag just about anything in sight make trying on clothes more complicated than it needs to be. Try smaller earrings, avoid jewelry with prongs, wear shorter necklaces and limit the amount of jewelry overall. If you want to make a dramatic statement with accessories you can do it with shoes, handbags and a bold ring or watch.
Shopping for clothes is often a race against the clock. I remember panicked customers practically flinging themselves at the salespeople in one womens' clothing store I used to work for with the announcement that they needed an evening dress for an event they were attending in two hours! Um, good luck with that. Even under less time pressed circumstances the clothes you wear shopping should be easy to remove and put back on. A jacket that easily zips off or a cardigan sweater left open over a lightweight fitted top like a tank top, or fitted T-shirt in a neutral color allows you to remove your outer layer easily and keep your top on if you are trying on something with sleeves. Pants should be loose enough to remove easily and slip on shoes are a real time saver.
Socks are another consideration when shopping. A pair of thin socks in a tan or dark brown color that blends in with your skin tone serves you well when trying on new shoes or just about anything else. I once saw a customer wearing white athletic socks look at herself in the mirror while trying on a super glamorous evening dress. The customer joked that she didn 't think the socks quite worked with the outfit. The truth is that it's hard to visualize how an outfit will look when you are wearing the wrong socks. A nude colored pair of socks virtually disappear instead of distracting from the outfit you are trying on.
As a courtesy to other customers you don't want to leave anything on the clothes that doesn't belong there. Using clear antiperspirant won't leave white marks on armholes the way white antiperspirant does. Wearing enough makeup to prevent unflattering fluorescent store lighting from making you look like a walking corpse is a good idea, but apply makeup with a light touch. The more makeup you wear the more likely some of it will end up on any garment you have to pull over your head to try on.
Don't wear perfume when shopping, going perfume free gives you the opportunity to try different perfumes while you are out shopping. Perfume is the one thing you can try on while shopping that doesn't require a dressing room, so spritz away!
