I wore this top for NYE: https://www.amazon.com/gp/product/B01M6WR79T/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 in navy and also bought one in camel. They're really soft and flattering!
These workout leggings are great too, I've heard they're a dupe for lululemons: https://www.amazon.com/gp/product/B01N643X2T/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
