From LAKE website: The Lolly Dress in Morning Blue, a pastel blue hue, is a Swiss dot gown that’s versatile and light as air. The updated smocked back accommodates a range of chest sizes, and additions like moves-with-you lining and on-seam pockets are practical enhancements for dressing up and down. Peep the pretty, pleated straps that complement its empire waist and square neckline — this style feels so right for a laid-back weekend itinerary that carries you from errands to cocktail hour. Made of 100% cotton. We recommend sizing down if you are between sizes or prefer a closer fit. Clothing should have a relaxed, comfortable fit when new. Size medium has a 48" body length, taken from the high point of the shoulder. The model is 5'10" and wears a size XS.
