To update your summer wardrobe without busting your budget, scoop up these sophisticated separates—all seven for less than $300. Track down a sleek silk tank to pair with tailored shorts, and look for the season’s essential T-shirt dress to double as both casual Friday and cocktail attire. Opt for a white-white tote to brighten up any ensemble, and for a safari-chic finish, top off with an armful of bangles or raffia heels.—Susan Cernek
