I definitely do not get up, shower, do my hair, put on a collared shirt, and then go back into my room and sit at my desk. The stock photos in this were jarringly non-candid for what remote work actually looks like.
I used to be that way, but now I do the full routine as if I were going into the office. I like it and I feel better about myself and more focused. I also am now very strict about having an actual home office which I go in from 9 to 12 with only my work computer, check out for lunch for an hour, then back in the office for the last half of the day with one break in the middle. This has made me really productive and let go of feeling like I need to be online all the time, working until 11pm, which I used to do because I always felt distracted and that I wasn't fully focused - in my boxers, watching Youtube and taking lots of breaks.
There's definitively a bigger expectation that women should dress up while at the office. Personally, I'll still wake up early, do my hairs and a put on a light makeup just for the 30 minutes long morning meeting. Sure, I'm wearing pajamas pants but you wouldn't know it.
Getting shower and dressed "for work" is most common advice given to people getting used to working from home along with keeping a regular work scheduled and having space dedicated to work.
Just because you or I may not get dressed up ... my wife certainly does.
