I have gone to every Dry Cleaner in Simi Valley, and normally go to Tempo Cleaners. Their alterations gal was very ill for many weeks, so I went to William the Tailor thinking they would care about Tailoring. I took a beautiful suit jacket to them to have the sleeves altered, the existing sleeves were vented with layered buttons. The seamstress told me she would make certain the finished altered sleeve would be vented and the buttons would be layered. I paid $37 to have the sleeves altered, and the sleeves were neither vented, nor were the buttons layered. I had to take the jacket as is at the time for an event, when I came back with another jacket in a different color to remind her of what it looked like and what she promised, and to have her correct the mistake, she told me that she could only provide a very small vent now. They should have called me if she could not do what she said she could do originally... AND, she should not have produced a finished product that did not include the two things she said she would do. The suit now looks cheap/shabby... and they made no attempt to refund or pay to have it corrected (I ended up taking it back to Tempo to have them correct her mistakes - I had to wait a long time for their gal to return, but they can do it?. Please do not make the mistake I made and assume that 'William the Tailor' knows anything about tailoring. They should change the name to 'William the Shuyster'.
