When we look back at the Golden Era of bodybuilding, we can see what kind of clothing & gym apparel was hot and stylish. Retro socks, specifically at the mid-calf area were super hot. Gym t-shirts, stringers, and tank tops were a huge hit during this era. As time progressed, we see very different styles of clothing in the gym. Back then they had track pants, track suits, all retro styled.
