OK, I'm going to throw in a little perspective here based on some of the comments I'm seeing in this thread with regard to the TFU changes. I came up wearing the "original" Dungarees, then experienced the switch to Utilities/Coveralls, but since I have been in college the past two years, I have not seen any of the NWU concepts in action.
First, let me say that the Dungarees were an outstanding uniform. Cheap, durable, looked good, fit well, cleaned up easily. The only downside was that, unlike every other services working uniform, we were never allowed to wear them off base for even short trips. (gas station, drive through, day care, etc..) Many also complained about the "Gas station attendant/prisoner" effect.
Then the utilities came allong. We were told that these would be a big improvement over what we had. Not true in every respect. First, they were twice as expensive as Dungarees were. Not necessarially a problem, if they last a while. They don't.
1) They shrink like you wouldn't belive. I wear 36 pants, but I had to buy 44 utilities if I didnt' want them to look painted on.
2) They fade. Dungs were supposed to do this. Utes aren't.
3) They are not durable. Don't even look at your Utes cross-eyed, or you will get holes showing up in random places.
4) They don't clean up. The shipboard environment is extremely dirty, and these uniforms simply did not clean up in the wash like Dungs would.
What we were left with was a "working" uniform that was completely unacceptable for its intended purpose. To top it off, we still were not allowed to wear them off base until about a year ago. Thankfully we did get the coveralls, which are accepted as the de-facto working uniform (at least for affloat commands). Of course, coveralls aren't even allowed off of the Pier. So, you'll forgive me for being pro NWU. There's no possible way it can be worse than the Utes.
Next, let's cover the space issue. It's all well and good to bring the bare minimum onto the boat the day you get u/w and have it fit into your stateroom/jo jungle with room to spare. Lots of junior guys live on the boat. They, not us, are the ones who will benifit the most from eliminating redundant uniforms.

As for SDK's, I'll admit they look good, but I couldn't see myself forking out the cash for a set if I didn't need to. If they become mandatory I'll get them, and I probably woln't even complain that much about it. (I chose the third poll option)
