I'm really chuffed with the armour customisation in-game. I'm really damn happy about hiding shoulderpads, especially considering the ones I kept getting didn't match at all. The only thing I'd actually really like to see is the option to hide gloves. (And if I've missed that, thread is worthless, woohoo!)
Basically, look at this shot:
And compare it to:
To me, the first looks a bit silly, as my character's arms are completely bare, but she's still wearing gloves. I could understand this would work if she were wearing a robe or top with long sleeves (as in the second screenshot), but with a short top, it just looks odd (and made screenshots annoying when I kept forgetting to take the gloves off =p)
I don't think this would be too bad of an idea personally, but I'd be interested to hear opinions. Also, as clarification, I'm not advocating hiding boots, trousers, pants or tops. I'm none too keen on seeing players fighting dragons naked.
