I am loving this shirt from J Crew, Thomas Mason. They make the best shirts and this will go with everything. The pants in the picture below are new from J Crew, Teddy, and they remind me of my all time favorite, Campbell Capri. The navy color is also a favorite. See them here. See the shirt here.
I also love this striped top which for me would be a wardrobe staple. I would wear this for years. See it here.
Adore this shirt from Middy n' Me despite its insane cost. This would look great with white jeans. See it here.
