Simple formula- Cold Wash / Air Dry / Hot Iron
Your dress will last for years if you wash it in cold water (hand or machine) and hand to "air dry." Never put your 100% cotton dress in the dryer for all cotton shrinks in the dryer. For a fresh and new look, use a hot iron to flatten any wrinkles.
*To ensure wear for years, clean and store your dress in a protective dust bag during dormant months.
