First day back at work - do you think a robe and fuzzy slippers is okay

I am just two weeks post-op but had lunch with 2 colleagues in my home today and I DREAD going back in a month. I cannot even fathom it. I have not worn any foundation garments for 2 weeks and cannot even imagine anything against my incision. I cannot even sit at my home computer for too long or I get sore and tired.
I say go as comfortable as you can get away with and tell your immediate supervisor and any direct reports that you need that for a while. Hopefully that will bring you physical and mental comfort so that you can get some work done

I work in a law office so I cannot be super casual at work. Until it got cold here, I wore dresses to work with thigh-high hose - pretty comfortable.

Once my scabs came off my incisions, I returned to my shapewear panties. My "girls" became smaller after surgery, so I decided to give up my underwire bras and found some that still give good support and are so much more comfortable.

Now I am in pants made of stretch material with an elasticized waistband. A long sweater set covers all sins!
