Help Dress Me? Please?

[caramia]

I want to start dressing more professionally at work, to make a better impression- I'm a departmental accountant at a university.  Right now, I wear jeans, sneakers, a t-shirt/cami, and cardigan most days, but I'd like to upgrade to business casual.  Any suggestions?  I'm mostly looking for pants & shoes.

I'm 5'2" & usually a size 8... I have big calves, so skinny jeans are out. I'd prefer heavier material for the pants, in a color that will help hide yellow lab hair.  It's pushing it, but pants with a comfy/stretchy waist would be great - I often have stomach issues or bloating so comfort is key.

For shoes, I need something comfortable & supportive.  I have bunions & wear orthodics, so heels are out. 

And I don't have a lot to spend.  I'd like to spend $50 or under per pair of pants, unless they're absolutely amazing.  Local stores are Macy's, JC Penney, Vanity, Maurice's.  I'm fine with ordering online if returns are free.

I appreciate the help
