Yep, the most important question. I scoured the internet and Facebook groups for information on what to wear...most specifically: shoes.
Since leaving my full time job last July, I did a (in hindsight) bad thing. I got rid of all my cute shoes that were business casual. "I didn't need them anymore," I'd said. 😑 <-- my face when I discovered the lie I told myself. SO, in addition to bringing my super-comfy grey TOMS (to wear after-hours)...this is what I did:
After reading a bajillion reviews and shopping around, I ended up purchasing some Dansko shoes in their 'Sam' style (in this Sand Dollar color). They were perfect from first step. My feet never hurt and they went with everything. I also bought some ridiculous toe socks that literally cover only your toes. They worked really well to absorb any unsatisfactory olfactory developments. Also, pro tip: putting panty liners in your shoes will also act as a "sock".
Besides the shoes, Blue Print was very casual (more so than Surtex, I thought), and I wore a combination of leggings, tunics, dark jeans, and comfy, flowy tops. So: get a shoe that's comfy and that is broken in. Mostly any shoe company that deals in comfort is your best bet.
