This 4XL sleeveless Tee started out black. After tying a complex creative pattern, I removed the black color and dyed the perfect color. This process is known as discharge dyeing, and it is not your usual tie dye results. The dye used is not the same type of tie dye kit from your childhood. We use Procion dyes, which produce vibrant lasting colors that make your garment last without fading. This piece is 100% cotton and perfect to dress up or down.
