Working for one of the best-funded startups in Los Angeles’ “Silicon Beach,” Chelsea decided to perform a social experiment with her work clothes.

She usually wore the same standard tech uniform as her male coworkers — jeans and a t-shirt — but felt she wasn’t getting treated with the same respect. Techie that she is, she conducted research — by switching to a more “professional-sexy” look.

“I changed my clothes for two weeks, and the response I got was incredible: My ‘work was improving. You’re doing a great job,’” Chelsea recently told TheWrap. “I should note for those two weeks I basically did nothing. I not only just changed my clothing, I probably decreased my work by, like, 60 percent.”
