THANK GOODNESS: Ah, Friday, the final fifth of a long, hard week. Friday means bagels in the break room and casual clothes all day long. It doesn’t mean, however, looking like an unmade bed at the office. Dress for (relaxed) success while keeping your professional cool with the help of a classic blazer. Pick a distinctive, tailored version like this American Living military-inspired jacket to transform jeans and a tank into meeting-ready attire in no time flat. Can you say “promotion”? GET IT: On sale for $44.99 (originally $65); available online from JCPenney.
