Various Shirt Fits

The fits of clothing can vary by brand. A size L T-shirt from one brand may fit differently than a size L T-shirt from another brand.

Most brands that offer plus sizes use a smaller size such as L as the base size and proportionally scale it up. This often results in plus size T-shirts with shoulder seams that are too wide and fall halfway down the upper arms. The sleeves may be too long, and the shirt may be too loose-fitting because it is oversized everywhere. At Alca, we understand this issue and have paid special attention to the fit of our clothing for men with larger sizes. Our T-shirts are designed for the larger man's body, providing a good balance between comfort and proportional fit. This ensures that the shoulder seams, sleeve length, back length, and total chest circumference are in proportion. The shirts have extra length in the front and additional room in the stomach area.

We recommend consulting the T-shirt and boxer shorts size chart to determine the correct size.
