Is it okay to wear the new T-shirt and work out right after receiving it?

Even if it does not rub off in a dry state, when sweat or moisture soaks in, color easily bleeds onto other fabrics. GOYOWEAR recommends washing it first before wearing it for the first time to prevent color transfer of the T-shirt^[1]. In addition, because color can rub off due to sweat when wearing it and working out together with light-colored clothing, it advises avoiding such wear and activities^[2].

Generally, fine dyes that did not completely fall off after processing may remain on the surface of dyed fibers. When sweat shed during exercise and continuous friction are added to this, the dye dissolves into moisture and stains adjoining light fabrics. Therefore, when you receive a new product, it is safe to first wash it alone to rinse off residual surface dyes, and to avoid layering it with light-colored clothes when doing exercises where you sweat.
