- Support: Built-in shelf bras and light padding can improve shape and support, especially for growing teens.

- Care and maintenance: Opt for easy-care fabrics that dry quickly and resist wrinkling for frequent pool use.
- Accessories and extras: Consider mesh cover-ups or color-block designs for versatility across pool days and beach events.
