Non-twinked newb Monk - armor or no?

[Kyosho]

So I've got a human monk to about level 6, and I keep struggling with whether to wear armor or not. The problem is that I want to loot my kills, and earn money, but looting ends up putting me over the weight limit pretty much instantly. I'm just wondering, whether, for now, if I should just forget about the weight limit and wear leather armor? If I do, at what point does that make me less effective?

I probably should have chosen a different class for one of my first characters, so I wouldn't have to worry about money. But I really like playing monks..
