Yeah I look like shit by most people's standards - really unbothered about it though tbh!
Don't do make-up, just wash my hair in the morning and brush it and leave it to dry itself, need a haircut as fringe has got far too long, put on about 2 stone in the past year or so, keep forgetting to tone and moisturise in the morning and can't be remotely faffed before I fall into bed at night... probably need to shave my legs and underarms atm now I think about it... Yes, I am redefining low maintenance 
I'm 34 and can't really get away with this lack of regime like I did when I was 20. I've never been a raving beauty and all the make-up and dieting and preening in the world wouldn't make me one, but I do think I have now reached the point where I should probably be arsed to do something... but I can't be! (arsed that is).
Fundamentally I think it's because... what's the worst that can happen if I look a bit crap?
I work in HE so there are women far dowdier/more eccentric-looking than I around in reasonably senior roles (academic women of a certain age by and large don't give a fuck, which I like) so it doesn't impact on my job prospects (not that I'm looking to move up at the moment anyway).
I suppose my partner might stop fancying me/have an affair... but to be frank the state of our relationship sometimes I don't think I'd really mind.
The things I mind about at the moment are: (a) being a good mother to my daughter and (b) trying to rediscover what I take joy in as I feel like I have marginalised myself into a reactive corner for so long I have forgotten what I actually like and who I really am, and become boring even to my own self. This bothers me far more than being a bit frumpy. I used to be funny; I used to be clever. Now I'm just dull and that bothers me.
And more trivially, appearance wise, I hate that I have a lazy eye. It's the one thing about the way I look that upsets me, and the one thing I can't do anything whatsoever about. Sod's law.
