Always take a size up when in doubt
Though you may feel as though you look heavier, you will actually appear much larger than you are in clothes that pinch your sides, indent your thighs, or force your breasts to unnatural heights. If it's simply the numerical size that troubles you, cut out the tags and bin them before your new clothes enter your closet.
Accentuate one key piece in an outfit
Don't pair all of your favorite wild, unique pieces in one outfit. Let one element truly shine— If you have a crazy pair of boots you love to wear, a large pair of earrings, or a bright top you can't live without, pair the piece with an otherwise understated outfit.
Invest in a classic handbag
Whether you own hundreds of handbags or find yourself using your pockets more than a purse- a classic, medium-sized, black handbag from an established fashion house such as Chanel, Vuitton, Hermes, or Bottega Veneta never goes out of style (it actually becomes more coveted as it ages) and always adds a touch of refinement to any outfit, be it an evening ensemble or simply jeans and a basic tee.
Designer labels and logos do not equal style
Evident labels or logos from expensive fashion houses do not give one 'instant style.' In fact, you'll look more like a nouveau riche billboard with a D&G logo'd tee, Vuitton LV logo handbag, and CD logo'd Dior boots rather than cool. Brand names or logos can be great, just ensure you are not head to toe in everyone's name but your own.
Practice makes perfect
If you buy a new pair of shoes for an upcoming occasion, a sexy nightgown to wear for your significant other, or even a formal evening dress— give your purchase a 'test run.' Wear the item around the house and find your comfort zone before wearing the piece in front of others. This will allow you to look more confident and will ensure you know how the item fits when you move, sit and walk. Come the day of the event or unveiling you'll feel more self-assured, which in turn produces a radiance others can't help but notice.
