I am not counting buttons, zippers, snaps or getting their shoes on the right feet but every 2 year old (and one 20 month old) I have can manage the basics.
When I diaper change, I hand them back their pants and have them do it themselves. Every single diaper change.
Diaper changes take a bit longer but in the long run it's more than worth it.
When we go outside, we get ready as a group:
"Okay little people, lets get our snow pants on first!"
"Nicely done little people! If you have an extra hand, let's help our friends who might be struggling"
"Okay, now lets get our boots on!"
"Next let's get our coats on!"
"Mr O, can you give Miss M a helping hand, she looks like she is struggling..."
"Once you have your coats on, you can start working on your hats first and then lastly your mittens while Miss BC comes around and helps everyone with their zippers and snaps"
I will start zippers but I won't finish them. Etc etc etc...
We do this every single day here....even in the coldest winter times....and even if we are only outside for 10 minutes.
Daily practice every day in ANY way we can helps tremendously and the proof is in the fact that I can manage 10 kids (ALL under age 5) get ready for outside play in less than 20 minutes. 
Yes, this is what I do, as well. This is a HUGE reason why I like starting the child at 12 mos rather than when they are older.
