We had a "no denim" rule, but it never seemed to be enforced. I totally agree with the "body type" rule and no visible tattoos. I feel as a whole dress codes have become too relaxed (in church, workplace, etc.) so I don't know if that will work just saying wear church clothes. The pictures of do's and don't s is a great idea. (I feel like a grandma and I'm only 24, but I really wish things were a bit more conservative at times. Especially when it comes to what to wear in certain situations.)
