There is no panic like the panic that comes from receiving an invitation with some vague dress instructions. Considering most of us don\u2019t work in the fashion industry, how the hell are we supposed to know what these instructions mean?! The worst by far is \u201csemi-formal\u201d. Is it half formal? It is almost formal? Is it an \u2018element of formal with an element of casual\u2019? The mere thought is giving me nightmares back to my first gymnasium dance in grade school. Thankfully the experts are here to help we plebs decipher this annoyingly vague instruction. This is a lesson in embarrassment avoidance! Take it from our expert, Ilaria Urbinati, one of the biggest LA celebrity stylists, on how to look killer for all occasions.\r\n\r\n\r\n\r\nThis West Coast celebrity stylist counts Chris Evans, Bradley Cooper, Joel Edgerton, Ryan Reynolds, James Marsden, Armie Hammer, and Rami Malek among her clients. She dresses these men for all their major life moments \u2013 weddings, premieres, award shows, press junkets and everyday life. She knows a thing or two about the million dress codes floating around out there.\r\n\r\nHere is her take...\r\n\r\n\u201cI would say \u201csemi-formal\u201d is a casual suit, maybe no tie or worn with a polo or knit and a more casual shoe. Like a more relaxed suit look.\u201d\r\n\r\nWhat should you consider when dressing for semi-formal?\r\n\r\nFor sure the season and weather play a big part. In the summer it\u2019s great to do a casual suit with no socks and maybe a low top white sneaker or boat shoe. In the winter, I love a wool suit with a sweater and a rough boot.\r\n\r\nWhat are your opinions on accessories or jewelry dressing up an outfit?\r\n\r\nI actually think the right kind of man jewelry is good for making a look feel a little more rugged and casual. A more casual metal band watch helps too. For a more formal look I love a dressier, thinner watch, and of course cufflinks and shirt studs for a black tie look.\r\n\r\nAny big trends in semi-formal dressing?\r\n\r\nI see more and more guys having fun with patterned shirts - there has been a big trend of throwing a Hawaiian shirt under a blazer (also looks great by itself or under a leather jacket for a very casual vibe).\r\n\r\n\r\n\r\nIs there such thing as overdressed for an occasion?\r\n\r\nDefinitely. Sometimes it\u2019s cool to be the guy who is always in a suit but you don\u2019t want to be the guy in a tux when everyone else is in a suit. For the Critics Choice awards this year the attire was black tie but I was dressing half the guys there so I decided to ignore the dress code and put everyone in suits instead, haha, I figured we had the numbers on our side. I like the idea of a guy in an awesome, slightly adventurous look surrounded by a bunch of guys in tuxedos who all look the same. But of course you can never go wrong with timeless.\r\n\r\nAny general dressing tips to share?\r\n\r\nWear what suits your personality - you can get away with so much this way. I have guys like Rami Malek who can pull off some really fashion forward looks that other guys can\u2019t, and I have some guys like Bradley Cooper or Joel Edgerton who are a little more rough around the edges and can get away with a slightly more thrown together rugged vibe that looks killer on them.\r\n\r\n\r\n\r\nWhat exactly do you do for clients?\r\n\r\nHaha, how much time do you have?\r\n\r\nAnything else to share?\r\n\r\nI love my clients - I get them and they get me. They know to let me do my thing and I know to respect their comfort zones just enough and push them out of it just enough. It\u2019s a real collaborative thing and it\u2019s very intimate to help someone express who they are through their style and honing in on that. Once that trust is there, especially with guys, it\u2019s sort of forever. I have clients like Chris Evans, Bradley, Joel, Ryan Reynolds, James Marsden, Armie Hammer etc that I\u2019ve worked with for nearly a decade. The fun part is to keep evolving their style and never get into a rut. That\u2019s a big part of my job and they know that I\u2019m always going to have some new thing I\u2019m wanting them to try out. It\u2019s meant to be fun, its just clothes.\r\nCheck her out\r\n \r\n\r\n\r\n\r\nIlaria Urbinati was born in Rome and raised in Paris. She started out in fashion at eighteen working for her aunt, designer Laura Urbinati, growing to become a buyer and manager for Laura\u2019s West Hollywood boutique. During her 3 years at the store, Ilaria helped make the store a fashion icon\u2014it was the first store on the west coast to carry designers like Balenciaga, Comme des Gar\u00e7ons and Helmut Lang. From there she became the buyer and manager for Satine, where she helped transform that store into a Los Angeles hotspot by introducing brands like Stella McCartney and Roland Mouret, while throwing events that drew top celebrities and industry tastemakers. She continued on to buyer and manager of Milk, where she again traveled to fashion weeks in New York City and Paris to secure the up and coming trends for the boutique. In the fall of 2008, Ilaria opened her own store, Confederacy, where she served as COO, co-owner and buyer. The store was an instant success, catering to prominent celebrities and musicians in addition to the growing fashion scene in Los Feliz. Her increased demand from freelance and celebrity clientele skyrocketed, and she made the decision to close the store at the end of 2013.\r\n\r\nAlong with her retail experience, Ilaria has achieved great success in design collaborations. She teamed with Albert Hammond, Jr. of The Strokes to create a limited edition line of suits. The line was written up in every major men\u2019s magazine including GQ, Details and Esquire, in addition to being the most prominent line worn by Ryan Gosling\u2019s character in the feature film Crazy Stupid Love. There was such a demand that the line sold out almost immediately, prompting Ilaria and Albert to collaborate on a second season, which also quickly sold out. Ilaria also co-designed Rebecca Minkoff\u2019s women\u2019s line for 2 seasons, as well as styled her runway presentations. She has also collaborated with Gucci and Ferragamo on custom designs for Bradley Cooper, Armie Hammer and Chris Evans.\r\n\r\nSince establishing herself as a force within the industry, top magazines and photographers began looking to Ilaria for their shoots and campaigns. Ilaria styled fashion stories for American magazines like GQ, W, ELLE, InStyle, V Magazine, Lucky and Details, as well as international publications like M: Le magazine du Monde, L\u2019Optimum, i-D, GQ Italia and InStyle UK. She has collaborated with photographers such as Ryan McGinley, Carter Smith, Norman Jean Roy, Mark Seliger and Guy Aroch, among others. The press also took note of her talents, writing profiles on her in W, ELLE, TIME, WWD, Los Angeles Times Magazine, The New York Times Magazine, VMAN, L\u2019Uomo Vogue, E! Online and Good Morning America, to name a few.\r\n\r\nWith such outstanding fashion credentials, it\u2019s no surprise that Ilaria has exploded in the celebrity world. She was Head Costume Designer for the first season of The L Word and has custom designed tour wardrobe for music clients Plain White T\u2019s, Alanis Morissette and Lady Antebellum. Her consistent and ever-growing celebrity clientele includes Bradley Cooper, Chris Evans, Bruce Willis, Ryan Reynolds, Armie Hammer, James Marsden, Will Arnett, Nikolaj Coster-Waldau, James Van Der Beek, Ty Burrell, Ian Somerhalder, Theo James, Joel Edgerton, Jason Clarke, Ben Affleck, Shailene Woodley, Nina Dobrev, Leighton Meester, Juliette Lewis, Marisa Tomei, Lizzy Caplan, and Laura Dern.
