Update: Interview clothes

I just got a call for an interview tomorrow morning at Walgreens as a cashier. Problem is I don't have any tan or dress pants. (Just put app in, thought I'd have more time to get stuff). I only have skinny jeans that are light wash, dark wash, black, or white. I won't have time to go shopping before my interview. Help!

Edit to add: I wasn't trying to dress like their uniform. I was just always told that tan dress pants were the most appropriate interview attire. But it's been 7 years since I've had an interview.

Just figured I'd update this post. I got the job! Start on the 18th. Haven't worked for 5 years so I'm pretty nervous but excited!
