With holiday season just around the corner, party dressing is top of mind. While a traditional cocktail dress might be appropriate for a New Year’s Eve soiree, some events—the office dinner, the luncheon with your in-laws—call for something festive, but a little more casual. Wearing a maxi dress is an effortless way to look formal instantly, but when you add a blazer over it, it’s an entirely different look. Just look to Bally’s SS15 Look 15. You can certainly just wear the dress, but a structured jacket grounds a flowing skirt and also add warmth, literally and figuratively. If the dress is sleeveless, you can even wear it through to Summer. Now that’s maximizing utility.
