I could conceive of many situations where one would be happy with the first tailor's work, but would still want to go to a second tailor. For one, different tailors have different styles and might specialize in different cuts or silhouettes. Different tailors might do certain details better, which would make you want to go to different people for different things. Heck, some people might just like sleeping around. It might be convenient for you to go to one tailor at some times and go to somebody else at other times.
I'm not saying that you should defraud the tailor or shirtmaker - of course not. But, it's kind of silly to say that you should only use one tailor or shirtmaker if you are happy with their work and anything less is disloyal.
EDIT: I also believe that it's possible to develop long-term relationships with more than one tailor or shirtmaker at a time.
