A dress code can help or hurt. Keeping some of the riff out, but making it to stringent can cause some problems.. We were working with creating a dress code including: No bandannas, any distracting articles, obscene shirts t shirts, nudity etc. Our hall was mid town , beer only 24hr , 18+ and within 4 blocks of the high school, next door to a bowling alley. It took us a LONG time to get approved by city, part of the agreement included the dress code we designed. It was very important that we remained a place that was attractive to familys.. 10k sq ft + a very large investment.
