Where can I find women's pants similar to the Puritan brand?

I start my job at Chick-Fil-A on Monday and my boss told me I need to buy black Puritan brand pants from Walmart for my uniform. Only issue is, Puritan is a men's only brand. He gave me two pairs of women's pants directly from Chick-Fil-A to try on just to see if they would work, but of course I'm the size in between the two. Are there any brands similar to Puritan brand that are for women? And preferably around the same price ($10)?
