What's My System?

It’s only Day 2 and I have already met an obstacle in my no repeating rule. How do I count an outfit as worn?

Most days, it’s easy. I get up, I put on clothes I haven’t worn before, and wear them all day. Simple.

But what about on days that I work? The current outfit I’m wearing I didn’t put on until 4 pm. I’ll only wear it about 6 hours AND I’m not even going to leave my house in that time. So do I still count the shirt and the pants as worn and thus unwearable until I finish my experiment? This won’t be an issue for much longer though—this is my last week of work.

And what about Sundays? On Sundays I wear my church outfit from 9 am-2 pm and then I change into something comfortable for the rest of the day. Do I count both outfits as worn? Or just my church outfit? Maybe I should rewear things only on Sunday afternoon—just to avoid this issue.
Any thoughts?
