Even though right this second I'm sitting here in trackies (but I have a clean Tshirt on!) I started this sort of thing a while ago. I was sick of feeling frumpy and awful. I went back to the gym (I realise not a desire of everyone, but something I enjoy) to do something for myself.
One thing that really makes a difference to me is having my clothes ready to go the night before. While that might not mean layed out, just washed and ironed and thought about is enough. Then as soon as I get up, I get dressed/showered and ready to go for the day. That staves off the PJ days for me.
In regards to the 'but I'm not going anywhere', throw it out of your thoughts. I get dressed for me, not to up anyone else's opinion of me, but because I like the way it makes me feel. So that I don't slink past any mirrors. So that I don't suffer insecurity and inferiority when I go out because I'm comparing myself to other people. Because, as vain as it is, I like it when my husband comes home and says 'gee you look nice today!'
