This dress style will make you look two sizes smaller

8. Become BFFs with your tailor
A tailor is arguably your most important asset when it comes to dressing thinner. A good tailor can alter anything you own to custom fit your body because, let’s face it, we weren’t all built like Gisele Bundchen. And if we  haven’t made it clear enough already, the right fit is everything. From shortening sleeves, nipping waists, hiking up hems, and even changing the fit of a winter coat, a tailor can work wonders on your wardrobe.
