Of course, you can and should wear whatever makes you feel comfortable, but INSIDER spoke with a few professional stylists who pointed out some of the clothing mishaps they see most often that can make an outfit go from fabulous to just OK, and how to fix them: "Sleeves should end just past the wrist bone. Even when an item fits perfectly everywhere else, a sleeve can be cut too long and make it look too big. This is an extremely common alteration that doesn't cost much and can make an item go from good-looking to tailor-made." Molly Dickson, Botkier style ambassador and celebrity stylist, told INSIDER, "I think that dressing for comfort is very important. If you are wearing super sexy high heels with a cocktail dress, but you can't walk, the look ultimately fails." Top Los Angeles stylist Laurie Brucker told INSIDER, "This is probably one of my absolute favorite styling tricks. By adding this style detail into any outfit, you elongate your legs, you slim your frame, and you instantly add style to an otherwise styleless look. The trick is to take the front half of your top and tuck it into your pants, then play around with the fabric so that it drapes softly over your pant line and around the back." Celebrity fashion stylist and co-found/creative and style director of Athleisure Mag, Kimmie Smith, told INSIDER, "Distressed pieces of apparel and accessories add a 'cool factor' to your look, whether it's rocker or vintage. But garments and pieces that truly look like they should have been recycled make you look unkempt." Keep the distressed to a minimum, and always add some glamorous accessories. Quinn said, "Vents are a design feature that allow a garment to easily move around you as you move and walk. They are sewn shut during the final stages of manufacturing to allow for easier shipping. Leaving vents sewn prevents proper movement in your coat and just makes you look silly. Snip the 'X' thread and pull the loose thread from behind to look perfectly polished." Brucker said, "Adding those final touches to a look can instantly update, revive, and excite any outfit. Statement necklaces and earrings are a great place to start for the beginner! I always say that when you wear clothes, it's just clothes, but when you put on the accessories, you make your look an intentional outfit with personal style." Fashion stylist and costume designer Tiffany Hasbourne told INSIDER, "A nice twist to it would be mixing your vintage sweater with a skinny jean or high-waisted pant to give it a current sleek look. "Going head-to-toe with a vintage look will have people looking at you like you are going to a costume party. Just be prepared to mix a little old with new when it's time to bring that beloved vintage item out of your closet." Brucker says, "Cuffing up your sleeves, whether it's a denim jacket or a sweater, instantly elongates balance out of your outfit. This especially works great for petites as it lifts the look and creates space. Cuffing up your pant hems has a stylish effect, especially when worn with ankle booties."
