## Definition

clothing that you wear for swimming, like a swimsuit or swimming trunks.

For teachers: clothing designed specifically for swimming or other water-based activities.

## Examples

- Don't forget to pack your swimwear for the beach.
- The hotel shop sells a variety of swimwear for guests who forgot to bring their own.
- Advances in textile technology have led to the development of professional swimwear that reduces drag and improves the performance of competitive athletes.

## Pitfalls

- Not "I bought two swimwear" but "I bought two pieces of swimwear" — Swimwear is uncountable; use 'pieces of' or 'items of' to count individual garments.

## Usage notes

- Uncountable; refers to the category of clothing rather than individual items.
