If "Couture" is the design of fashionable clothes to a person's specific tastes and measurements, then "Lake Couture" is expressed as clothing explicitly designed for life on the lake with a casual and artfully stressed rugged flair. Each "Lake Girl" or "Lake Guy" likely has their favorite shoes to protect their feet and deal with water and walk on boats. It mixes bikini tops, shredded cut-off shorts, cropped shirts, hoodie sweatshirts, lifestyle quotes, and maybe a touch of sparkle, depending on the lake region.
