For example, if you’re attending a wedding in late August, you’ll want something that will keep you cool in the heat but covered up at night. In this case, consider opting for the Zenni Dress. The bright champagne color will reflect the sun’s rays, but the high neckline will keep you comfortable when temperatures drop in the evening.

From early summer to mid-autumn, you can experiment with more seasonal tones and longer lengths like this lightweight Ronda Silk Dress or this open-slit Baxley Dress.

When winter comes around, avoid leaning into dark, heavy tones, and opt for colors that match the nature of the occasion. For example, this cool-toned Frankie Linen Dress can be paired perfectly with a cozy shaw and your favorite pair of strappy heels.
