This one is comfy and long (no crop tops for me please! showing shoulder is enough) and light and breezy and also looks great with jeans #summerinsanfrancisco but i here's a few others I'm lusting after that are all under $100:

BlackPurple flower print (pre-order)
Black and Big white flowers with short sleeves
