[Mass Effect] Why don't the Volus customise their suits like the Quarians do?

Seriously, it's hard enough to tell those dudes apart as it is.

The Volus don't have to spend all their time in their suits. They wear them in low pressure environments for safety, but on their own ships, their own residences and their own worlds, they dont wear them. The suit is, to them, the same as a space suit or diving suit is to humans. Combine that with their more cost-minded economic philosophies, as well as their socia structure, and there's no real need for them to personalise their suits. 

On the other hand, Quarians basically treat the suits like a second skin. Even on their own ships, the Quarians are stuck in their environment suits. They are as much a part of their individual identity as their voices, and they aren't interchangeable.
