Which of the following brands is NOT focused on swimwear?

The brand that is not focused on swimwear is Charvet. Charvet is a high-end textile and clothing brand that specializes primarily in formalwear and luxury shirts, particularly known for its ties and custom shirts. They tailor their products more toward sophisticated menswear than recreational or beach apparel.

In contrast, Chubbies is widely recognized for its swim trunks and casual summer wear, while Chrome Industries focuses on practical, durable clothing designed for cyclists and urban commuting, which sometimes includes swim-related products. Chanel, while renowned for luxury fashion in general, has a notable line of upscale swimwear that reflects its brand aesthetics under the haute couture umbrella. Therefore, Charvet stands out as the only brand listed that does not have a significant connection to swimwear.
