Putting together a grey shawl cardigan and dress pants is a fail-safe way to breathe personality into your day-to-day styling collection. If you don't want to go all out formal, introduce a pair of black leather low top sneakers to the mix. Keep this ensemble ready to go come warmer weather, and rest assured, you'll save time trying to pick out what to wear on more than one morning. As you're transitioning from your 20s to your 30s, you want to start dressing more professionally. In this case, outfits like this are ideal as inspo.
