Formal casual- if that’s even a thing…Please dress your best but don't outshine the bride (please don't wear any white). Since we don't have a bridal party, guests can wear our wedding colors which are earth tone greens. 
Steer clear of anything too casual. 
I get it, especially spending a lot of the past few years at home. No one wants to quit their coziest clothing like yoga pants, slippers, and worn out jeans. But these have no place at a wedding. Even though our wedding is casual and relaxed, please dress with respect. No flip flops, shorts, or worn out jeans should be on list of options. Instead, ladies, find a casual dress or dress slacks. Men, you can wear your best jeans without wear and tear and a nice shirt.
