OP could have been more discreet. No reason to mention the tailor of the original shirt. Just ask for a 'good, cheap tailor to copy a shirt' or something to that effect.
While I do not find the request untoward(Cleric?) it is just unnecessary to bring up the Cego name as Carl seems a decent fellow(I am not a client) and does not need to know about this.
But #3 on that list is great.
