You found the perfect top, then caught a glimpse of your arms in the mirror and swapped it for something with longer sleeves. Sound familiar? We've all been there, and it's the fastest way to talk yourself out of an outfit you actually love. Enter: Three-quarter-sleeve blouses. With loose and drapey sleeves, these blouses disguise arm jiggle without making you look like you're hiding. The cut hits right below the elbow, covering the area most women feel self-conscious about while still looking polished and pulled together.
