I dress up quite decently when I am at home. I think it is quite good of oneself to dress well and look appropriate even at home as it makes it look like you clean yourself for your own sake rather than for others. I only don't dress up very well at home if I am very ill and do not have the strength to wake up from sleep.
That is a good argument shilpa, I guess it depends on each one personality, in my case I simply don't care, I prefer to be comfortable than to look good at home.
