And if you need to easily dress down this outfit with footwear, why not introduce a pair of white and navy low top sneakers to your ensemble? So as you can see, it's a neat, not to mention spring-ready, look to keep in your transitional rotation. So if you need outfit ideas on what to wear as you go into your 30s, this pairing is definitely worth saving for later.
