The best tennis dresses do much more than serve you well on the court. As one of the best exercise dresses, they certainly bring posh energy to a match. But they're also the ultimate sporty-chic look for a weekend out and about, a hot girl walk, or a few hours of errands. Of course, the timeless appeal also qualifies them as a modern preppy style essential. Meaning? The best tennis dresses appear perfectly elevated with a blazer, varsity jacket, or sweater tossed over the top with a pair of loafers or chunky lug soles for a daytime event or dinner.
