Dear 100 Hour Board,
What are the current missionary dress standards? Do guys have to wear ties (not bowties, not just a shirt)? Do girls' skirts still have to be below the knee even when they're sitting? Are there restrictions for hair styles? Do missionaries have to have either natural colors or un-dyed hair?

A thorough rundown of missionary dress standards can be found here, and, as you've probably guessed, they're much the same as they've always been. Men still have to wear white shirts and ties, women's skirts have to fully cover both the front and back of the knees while sitting, and hairstyles shouldn't draw attention to themselves.
The biggest change in recent years is that women are now allowed to wear dress slacks instead of skirts in some missions, mostly in mosquito-dense areas. This change happened in response to the outbreak of Zika in Latin America in 2015.
