If you’re looking for shirts that are tight around the chest and arms but loose around the stomach, you may want to consider trying the following options:

1. Athletic Fit or Tapered Fit Shirts: Look for shirts labeled as “athletic fit” or “tapered fit.” These shirts are designed to accommodate a more muscular upper body while providing a slightly looser fit around the midsection.
2. Performance Apparel: Brands that specialize in performance or athletic apparel often offer shirts with stretchable and moisture-wicking fabrics. These shirts tend to have a tighter fit around the chest and arms but offer some room around the stomach area.
