To me, a baby tee is the perfect foray into the world of crop tops. To keep the overall effect sophisticated, I'm for pairing one with a blazer-and-shorts set (this pair of shorts has a high-rise waist and is meant to fit loosely over the thighs) and finish with bold but polished accessories like a patterned pump, structured bag, and sculptural hoop earrings.
