Loose dresses are a type of clothing that is often characterized by its relaxed fit and comfortable fabric. Muumuus, SACKS, alines, and CAFTANS are all types of loose dresses. Muumuus are typically long, shapeless dresses with a high neckline and no waistline. SACKS are similar to muumuus but have a more defined waistline. Alines are loose-fitting dresses that are fitted at the waist and flare out towards the hem. CAFTANS are long, loose-fitting dresses with wide sleeves and an open neckline. All of these types of loose dresses are popular for their comfort and versatility.
