My funds don't currently allow it, but if they did, I would purchase Nanette Lepore's "Kissing Coat." I love the belted cuffs and back, the buttons down the front, the cute pin-tucks at the high waist, and the perfect longer length. Made from cotton, it comes in the pictured white. I'm not sure if white is appropriate quite yet, but it will be great in a month or so. Unfortunately, the coat is an insane $550. Find the coat here.
Neiman Marcus pairs the coat with Nanette Lepore's "Picnic Pique Pants," which are also vegan-friendly and also adorable and very work-appropriate. Made from cotton, viscose, and elastane, and lined with acetate. They are $295; find them here.
