As another who works from home, my WiW's focus on what I wear when I actually get a chance to get out of the house and do something fun, or go into the office.
I do have a substantial "exercise gear" capsule I've built up over the years but I can't understand wanting to wear work out clothes all day long. I don't find them comfortable - especially workout bras. And after a workout I just want to strip the sweaty thing off.
My work-at-home capsule is really just a bunch of mix and match cotton loungewear - worn sans bra - so you don't really want a WiW with that. Heh. My hair is often back in a headband. No make up.
Since I spend so many long days working at home, toiling away at computer & endless conference calls, IF I'm leaving the house (and days can go by when I don't get a chance to get out of the house), whatever the reason, even to run errands, I am going to get dressed up. Hair done, make up the whole nine yards. I have to do that, for my sanity!!
I am just so glad my amazing DH is such an extrovert, and doesn't mind going out on weeknights after he's put in a full busy day at his office. There are days when he comes home and I'm so itching to get the heck out of the house to socialize... and I'm sitting there all dressed up and ready to go ("but first do you mind taking a pic for YLF before we leave?")
It was, of course, much different when kids were little and needed driving around because they didn't have driver's licenses and lives of their own. But they are in college now and it's a whole different life.
As for repeats, I repeat outfits all the time - entire outfits. I don't bother to take another pic and post it here, since it seems redundant. Everything I have posted recently I have been wearing to death. And, one bonus with the way my lifestyle is right now -- I can actually get away with wearing the same outfit twice in one week, if I feel like it.
Final note: I do agree that coming here can up the desire to buy and acquire. That is one of the reasons I took a long break. I started losing enthusiasm, I needed to watch my budget due to job uncertainty, and also I'd reached a point where I felt my wardrobe was all set. I came back precisely because I realized that my wardrobe was needing an upgrade again -- it was time for newness and refreshing. But I hadn't been paying attention to the trends, so I came here to get quickly up to speed. And it's fun all over again. When it's not fun anymore, I'll leave for awhile again.
