You can take off the clothes off other characters, but they need to be sleeping. First, you need a paralyze spell, an invisibility spell and have enough space in your inventory so you don't get over encumbered. After having those, wait till the person you want to take the clothes off is sleeping. Sneak in their house and stand by their bed (might want to save the game in case you mess up). While they're sleeping, use the paralyze spell on them then quickly search them. You will find that their clothes that they are wearing will be there. Take it then go invisible. Then they will go back to bed and their clothes will suddenly disappear (only the outer layer; don't get your hopes up).
If it says they are fleeing, then load the game and try again. Make sure you aren't invisible while doing it. It works on the people in the Dark Brotherhood sanctuary.
Note: It only works on certain characters.

A fast way to get up any magic except destruction is use the disired magic spell next to a bed and when magicka is empty sleep and regain it...easy

You can get up your heavy or light armor by getin a small bounty (lowest I've ever gotin was 5 by geting caught by a guard picking a lock) and then resist arrest and let the guards attack you(but don't attack back as that will just increase you're bounty!!! So just stand there) and when your low on helth just pay the bounty...also make sure your armor has good helth because if it is really badly damaged you wont get up any exp.... You should also put the game difficulty to the easyest so they take down less life...you can also get your block up doing this as well as your armor skill(smithing) by fixing your armor after wards...
