THANK YOU!!
I am clueless but used these boards for guidance!

This is a guideline for tipping your vendors for the day of your event. Keep in mind that this is a guideline and you should give a gratuity based on performance of their services. If you feel that a vendor has gone above and beyond, then feel free to give more and vice versa. Also, check your contracts to see if a gratuity was already included. A general guideline is 15%-20% of fees paid.

Makeup- $40-$50
