Which brand primarily offers t-shirts, casual shirts, pants, and sweaters?

The correct answer is Fjallraven. This brand is well-known for its versatile outdoor clothing, which includes a variety of essential casual apparel such as t-shirts, casual shirts, pants, and sweaters. Fjallraven focuses on functional, durable, and stylish pieces that are suitable for outdoor activities and daily wear, making it a go-to choice for consumers looking for quality casual clothing.

Fabletics, on the other hand, specializes primarily in activewear, offering sports bras, leggings, and workout attire rather than general casual apparel. Fear of God (FOG) is recognized for its high-end luxury streetwear, which may include more specialized and fashion-forward items but does not focus as heavily on basic casual apparel. Figs concentrates on medical scrubs and apparel designed specifically for healthcare professionals, which doesn't align with the general casual clothing category. Thus, Fjallraven stands out as the brand that aligns best with the categories mentioned in the question.
