Ready for a mind-blowing fashion hack? According to Lauren Edelstein, Style Director at Shopbop, all you need to do to determine whether or not a pair of jeans will fit is to wrap the waist around your neck — if the ends meet without overlapping (or stretching), they'll fit your waist. "The neck trick is one I was skeptical about, but it really works!"

Hate complicated fashion trends that only seem accessible to models and actors? It takes just three items to make literally any outfit look great, according to The Ambitionista's Heidi Nazarudin. "A face-flattering pair of classic sunglasses (preferably black), a gorgeous everyday leather handbag, and a smart pair of shoes you can easily walk in."

Neckerchiefs can take the place of a statement necklace if you want a warmer alternative to jewelry accessories for fall and winter. "They're bold, bright, and eye catching, too, but feel a little more special," says Edelstein. "And bonus points if you pick a vintage one!"
