Shirt - A henley tee in eggplant is a subtle yet strong color combination with the skirt. $50 from White House, Black Market.
Sandals - You're at home, you don't technically need shoes, but these flat brown sandals with an ankle strap are too cute. $95 from Seychelles.
Headband - Subdued brass leaves are casually festive from Anthropologie for $28. I always like to wear my hair up when hosting a party. Looks fancy and it's kept out of the way.
