Wedding gown yellowing is caused by a chemical degradation of the original fibers that compose the fabric. Over time the colourless chemicals that are within the fabric begin the inevitable process of decay and can become light to moderately yellow in colour or even a darkish brown.
This 50 years old dress was given to me just two days ago to restore by #handwash only, as a surprise for my customer’s mother, whose dress it is, as a gift for her Golden wedding anniversary in 2 weeks time! I wish I could be there to see her face when she opens the box to see her dress looking like it did the day she wore it
