Square or blocky-tipped lipsticks are showing up all over the place, and it's not initially clear why you'd ever want to use a product that doesn't actually follow the shape of your lips. Here's the thing, though: these square tips aren't as good for quick daily application, but they do offer a great deal more control, and if you apply your lipstick with a lip brush, they load your color more evenly. Basically, if you're getting ready for a big event, really want a precise line, or use brushes instead of the stick itself, they're a superior choice. If you're curious to see whether you're hip to square lipstick, there's a wide range of options, from fancy products like new Hourglass Femme Rouge Velvet Creme Lipstick ($30) to bargains like Avon Mega Impact Lipstick ($8).
