Bra & Bralette sets are basically sexy little bra & pant sets which come in sizes from small to 5xl cup sizes, and are usually underwired and slightly supportive. On the other hand, bralettes are not supportive and usually not underwired. They are very relaxed to wear and may be slightly padded. In general they may be worn as outerwear, or for relaxing.
