Band Concert Uniform

Due to some disagreement , the concert uniform is now on a top and slack basis .
Feel free to throw in some ideas . Any detail given will be appreciated and is very important .
Here are some of my ideas , do comment and tell me what I can do to improve the design .

1 ) We can reuse our silver concert uniform which was used during the 2009 concert , ( But since this year will be our first concert after we moved on to a symphonic band , I think most of you would prefer a new one perhaps ? )

OR

2 ) Something like the one below but not too ( big ) and a different colour .
Bottom : Black slack ( Tugged in )

OR

3 ) A more formal top ?

ps : Please leave some comment and ideas :)
Thank You .
