No matter how formal orinformal theworkenvironment,the way you present yourself has an impact.This isespecially truein first impressions.According to researchfrom PrincetonUniversity,people assessyour competence,Trustworthiness,and likeability in just a tenth of a second,solelybased ontheway you look.The different between today’sworkplace and the“dress for success”era is that the range of optionsis so muchbroader.Normshaveevolvedandfragmented.In some settings,red sneakers or dress T—shirts can conveystatus;inother not somuch.Plus,whatever image we present is magnified by social—media services like LinkedIn.Chances are,your headshots are seen much more often now than adecade or two ago.Millennials,it seems,face the paradox of being the least formal generation yet the most conscious of style and personal branding.It can beconfusing.So how do we navigate this?How do we know when to invest in anupgrade?And what’s the best way to pull off one that enhances our goals？Here are some tips:
1.As an executive coach,I’ve seen image upgrades be particularlyhelpfulduring transitions—when looking for a new job,stepping into a new or morepublic role,or changing work environments.If you’re in a period of change or just feeling stuck and in a rut,now may be a good time.If you’re not sure,ask forhonest feedback from trusted friends,colleagues and professionals.Look for cues about how others perceive you.Maybe there’s no need for an upgrade and that’s OK.
2.Get clear on what impact you’re hoping to have.Are you looking to refresh your image or pivot it?For one person,the goal may be to be taken more seriously and enhance their professional image.For another,it may be to be perceived as more approachable,or more modern and stylish.For someone moving from finance to advertising,maybe they want to look ore“SoHo.”（It’s OK to use characterizations like that.）
3.Look at your work environment like an anthropologist.What are the norms of your environment?What conveys status?Who are your most important audience?How do the people you respect and look up to prevent themselves?The better you understand the cultural context,the more control you can have over your impact.
4.Enlist the support of professionals and share with them your goals and context.Hire a personal stylist,or use the free styling service of a store like Crew.Try a hair stylist instead of a barber.Work with a professional photographer instead of your spouse of friend.It’s not as expensive as you might think.
5.The point of a style upgrade isn’t to become more vain or to spend more time discussing over what to wear.Instead,use it as an opportunity to reduce decision fatigue.Pick a standard work uniform or a few go-to opinions.Buy all your clothes once with a stylist instead of shopping alone,one article of clothing a time.
