A colleague stated that my answer has the "wrong tense" and is "not idiomatic". These posts are in response to his comments. So let me start with the first issue:

In this particular case, we are not talking about verb tense. As mentioned earlier, the term in question has nothing to do with verb tense. It's a noun phrase consisting of a verb plus noun. I'm assuming he meant the use of the verb form "commute" versus "commuting". If that's the case, the gerund is what we are talking about. To make sure there's no confusion, I quote a grammar source:

"Gerunds are formed by adding “-ing” to the verb: “sleeping,” “drawing,” “swimming.” But they are not the “-ing” verb forms that you see in the present or past continuous tense. They look the same, but gerunds are actually verb forms used as nouns." Examples: 1) "Legal driving requires a license." 2) "I like swimming." 3) "Sleeping Beauty and the Seven Dwarfs", etc.

Now, the question is whether we should say "commuting uniform" or "commute uniform", and I hate to say that the English grammar is not clearcut in this case. Compare:

a pool used for swimming: a swimming pool
a tower that leans: a leaning tower (e.g. the Leaning Tower of Pisa)
an address used for mailing: a mailing address
a board used for skating: a skateboard
a board used for surfing: a surfboard
a uniform used for commuting: a commute / commuting uniform

It seems to me that what makes the use of an expression idiomatic is the fact that it's used by native speakers of the language. In this particular case, there are examples of the expression with and without the gerund. Who is to say that one is more idiomatic than the other? Obviously, if native speakers are using both, they are both idiomatic and totally acceptable.
