That is not a good idea.
The thing about clothes is that they're part of a routine. I.e. I wake up, make some tea, put some fresh clothes on, turn on my computer, and now I'm in work mode. Ideally. In practice it doesn't always work like that, but it's still far better than waking up and just sitting down in front of my computer. Having a routine is really important for not getting lost.
They don't have to be business clothes or whatever, but just something fresh for the day. I'm the sort of nerd that wears chinos and a button up shirt even though I work from home and don't have video calls.

In addition, blurring work and personal life isn't good. You ideally don't want to work in the same room that you sleep, but this can't be avoided sometimes.
Variety is also key. Sometimes I go out and get work done from a local cafe for a change of pace.
