Sure, most of the time models are wearing designer clothes that cost hundreds of dollars, but even if your budget doesn’t go beyond the sales rack at Macy’s you can still look fab. The key: getting a perfect fit.

It may sound crazy, but spending a couple dollars to have your clothes tailored can make a HUGE difference. Prommer says, “If you have a sundress that you love but the straps are a little long, consider taking it to a tailor to have them shortened. It only costs about five bucks, and you’ll be amazed at how much better you feel about yourself when you don’t have to tug at the bust of your dress all day long.” Remember, fidgeting does not equal sexy.

Another tip to always look your best: Posture (yes, mom was right). “It seems simple, but walking and standing with confidence will also make your clothes look better,” Prommer says. “If you slump your shoulders, it automatically pushes your tummy out, and that’s not a flattering look no matter your size.”
