No, I don't underestimate it, but I realistic too!
In real life, me in the morning: shower, brush my teeth, brush hair, get dressed and go.
DH, in the morning: shower, brush teeth, SHAVE, brush hair (or whatever he does to it), get dressed go. Plus has to go to barber once a week.
Me: chose clothes depending on the weather and the temperature, DH wears a suit.
In the real world, we are both taken seriously, but the one who has to spend longer getting ready is not me the female. If I fancy wearing make-up, I can, but I usually don't bother, I'll try to go to the gym at lunch time or after work.
All the men in my team are expected to be suited, shaved, have a decent hair cut, not look like they have slept in their shirt. I can turn up in a (smart) tshirt, a pair of trousers and flats and I still look great. No one is checking if I've have shaven my legs that day.
I am getting bored of people pretending that women are exploited and need to present a different image. If you are not bothered, by experience I can tell you that no one else is either, as long as you are business smart.
