Entrepreneurs Agree: Everyone Should Own This One Piece for Work

It would be impossible to sit here and declare that everyone's work wardrobe should look the same. Given that dress codes vary widely, from strictly corporate to relaxed casual, an outfit that works for one office might not work for another. But no matter what your work environment warrants, there's one clothing item that's been deemed an absolute must-have by women who successfully founded their own businesses: a tailored black blazer.

We interviewed seven stylish women behind the businesses we love as part of our Female Founded series (which you should definitely check out, if you haven't already). Each of them shared their personally valuable pieces of advice on how to dress powerfully and professionally, but almost everyone agreed that a solid black blazer was the number one piece to invest in for work and beyond. Below, read what they have to say about this key piece.

Our very own Clique Brands co-founder Hillary Kerr: "A really beautifully tailored blazer will get you through so many situations. Wear it with a skirt or trousers for more formal days or with jeans for a more casual look; it's so versatile and will always ensure you look professional."

Finery co-founder and actress Brooklyn Decker: "If all else fails, a T-shirt and a blazer will serve you well—in the office and out."

CultureBanx founder Kori Hale: What's the number one piece to invest in for a work wardrobe, we asked? "A good blazer that can be worn year-round."
