First a combination of laces and different fabrics are sewn together into the style of garment desired. All outfits ordered in a certain color go through the process at the same time. Temperature, humidity, and wind from one day to next can vary the dye lots. The aging process is labor intensive. The garments are first dyed, then a brush is used to antique the edges.
Lighter colors are always softer, with less visual antiquing.
Water spots and streaks are part of antiquing and in no way to be considered to be a flaw. The different fabrics grab the dye differently, resulting in shadings. They all match in hue, however, they are darker or lighter. A monochromatic affect is achieved with various shadings - an antique look. The garments you choose will be made and dyed especially for you.
