Days spent working, running errands, lounging, or going out with friends all call for different looks, unless you can find a multi-tasking outfit that covers all your bases. We love how influencer Erika Boldrin styled her basics to create a casual-chic look that works in almost any situation. Black straight-leg jeans, a classic blue button-down shirt, and a blue sweater tied around the shoulders make great use of simple pieces, while round sunglasses and blue heeled sandals incorporate spring trends to take this outfit to the next level.
