Which of the following is a clothing category offered by the brand Bylt?

Bylt is known for its focus on creating versatile and functional clothing that often caters to a casual and active lifestyle. The brand specializes in categories such as activewear and casual apparel, which include polo shirts that embody both comfort and style. Polo shirts are commonly associated with a laid-back yet refined look, making them suitable for various occasions, from casual outings to more semiformal events.

In contrast, evening gowns, business suits, and formal shirts do not align with Bylt's core offerings. These categories typically involve more formal and traditional styles that are outside the brand's focus on casual and versatile pieces. This establishes polo shirts as the appropriate choice for Bylt's clothing categories.
