I'm all about comfort on the 15+ hour flight from Houston to Auckland. It is an overnight flight, and even with SkyCouches on Air New Zealand (which are the best, btw!) it isn't exactly comfortable. I'm adding another kid friendly shirt into the mix, too, mainly because I'm starting to freak out a little.
Lululemon Olive Mock Turtleneck: This is perfect for hanging out with the kids, and I love how it wicks moisture in the weird airplane climate. It will also double as a layer when I'm going to and from yoga in Auckland. (similar item linked)
Scarf: Grey ombré pashmina (similar item linked)
Shoes: Adidas Ultraboost X
