On steamy summer days the last thing you want to do is put on hot work clothes that seem to shrink as the day drags on. Let us suggest this Marc Jacobs "Kaleidoscope" Stripe Silk Dress ($398). The a-line silhouette is guaranteed not to stick to sweaty thighs, and the ¾ sleeves will keep your armpits from sweating through your dress in 8am traffic. Did you know that silk is one of the most comfortable fabrics you can wear when the thermostat rises? In this dress you will be cool, and collected for those afternoon meetings and as a last note: the ruffles & bold print are a totally refreshing take on office wear.
