Which brand is known for offering a variety of garments including polo shirts, pants, jeans, and swimwear?

The brand known for offering a diverse range of garments including polo shirts, pants, jeans, and swimwear is Kiton. This Italian luxury fashion house specializes in high-quality menswear and is recognized for its craftsmanship and premium materials. Kiton extends its product range beyond just formal wear to include more casual and leisurewear, which is why their collection features garments like polo shirts and swimwear, catering to different lifestyle needs.

In contrast, while Kith is known for its streetwear and could offer some more casual pieces, it does not have the same emphasis on a wide range of garments that include swimwear. Klim focuses primarily on outerwear, particularly for motorsports and outdoor activities. Kjus specializes in ski and golf apparel, which is also more niche and doesn’t encompass the variety seen in Kiton's offerings. Thus, Kiton's comprehensive range across categories is what distinguishes it in this context.
