Hoodys belong to the pajama family. Not to be worn in public. Especially never to an interview, even if it's Saturday. Yes they keep you warm and on a cold construction site, a hoody might be a good idea.
True incident. A Civil estimator 35 yrs old, commands $120k plus salary, showed up at Red Robin for a Saturday interview, - with a hoody on, to meet my (older) client. Oh happy day. He wants to build our highways and bridges and be an integral part of a $200M heavy civil company’s future.
Hoody's are generational clothing. A hoody is not on your Grandma's serious clothing list. Wear what you want, just remember you can't control what other people think.
Go to the GAP or Tommy Hilfiger, buy a uniform. It includes, straw colored khakis, dark blue heavy polo shirt and deck shoes. That's all you need to pass the social acceptability test. I think it applies to both men and women, you can adjust that to taste. Don't dress for yourself, dress for the outcome you want. Fashion is always working, - either for you or against you, but it's working.
Try and look like you take other people and life seriously.
