We all want comfort when it comes to styling, and this laid-back pairing of a navy and white print crew-neck sweater and skinny jeans is a practical illustration of that. And if you wish to easily dial up your outfit with one single item, why not throw a pair of plimsolls in the mix? As the weather starts to warm up, it's time to get rid of those bulky winter gear and choose something lighter, like this look here. This outfit demonstrates that in your 30s you have a vast array of styling options.
