2. Buy clothes in the right size. Sometimes, we’re not happy with the number on the tag, so we end up buying clothes that are too small. Newsflash: Every brand sizes differently, so if you’re shopping in a cheaper store, you’ll definitely be a bigger size than if you buy designer. Plus, buying a pair of jeans in a size 2 won’t actually make you look like a size 2 if they don’t fit. You’ll just end up with the dreaded muffin top. We promise, sizing up if need be will make you look a lot leaner in the end.
