Shattered Kingdoms

Is there a game mechanic reason not to wear armor/clothing that's a size too small on a character that isn't planning on being in melee combat at all? Other than looking sort of like a bodybuilder or stripper, I can't seem to think of one.

Not to my knowledge it can also make you a much more efficent
hoarder.

If you don't *plan* (key word!) on being in melee combat, I don't think it matters at all.

Here's hoping that works out for you!

I'm thinking that the silks, cloths and whatnot that my current is wearing won't help that much even if they are the right size

The biggest (pun!) reason I could advise against wearing things tight is that there are times where your size will get screwed up, and going from tight to unwearable in the wrong situation can be a real pain.

I heard a rumor that poorly sized items are less effective: armors offer less AC, weapons attack less reliably, etc. I don't know if that is true, but it makes sense.

I tend to measure how much damage a given NPC does to me, and I vividly recall a NPC that would always take me down from 100% to about 50-40% every time I fought him. I discovered that my armor was the wrong size, resized it, and that NPC began to always take me down from 100% to 70-60%.

It's standard practice for casters to keep their clothing one size small so that they can be better at hoarding. If you don't plan on getting hit, go for it.

What if you do plan on being hit? Like if you are a melee class like a barbarian or a fighter or a swashbuckler?

Then you probably want the full protection that your mithril thong has to offer.

Do not ever wear armor that is not sized properly if you are a melee class.
