A white crew-neck sweater and white jeans are the kind of a no-brainer off-duty outfit that you so awfully need when you have no time to dress up. Add a pair of dark brown leather desert boots to this outfit et voila, this look is complete. As you're moving through your late 20s, you probably want to start dressing more maturely. If that's the case, combos like this are a goofproof option.
