Hallo RexV und sfpugh!
sfpugh is right about the Hose vs. Hosen conundrum: the singular die Hose "the pants" is used to talk about one pair of pants in German, and the plural (die Hosen) is used for more than one pair of pants. (You may sometimes hear die Hosen used for just one pair of pants, but this wouldn't be standard usage.) So in the sentence you are trying to create, RexV, it should indeed be Hose and not Hosen. (Thanks for sharing your reference for weak nouns, sfpugh!)
There is also a typo in the German word for "tailor" in your sentence, RexV: careful to include the N in Schneider.
Also, your original sentence in English actually starts out with an infinitive verb - "to visit." So in German, you should use the verb, besuchen, rather than the noun, Besuch.
Thus, the final version is: Besuchen den Schneider mit meiner Hose und meinem Hemd.
I hope that this clears everything up!
Bis zum nächsten Mal,
