Vin is right. Smile and nod your head.
Nobody has figured out why a wife needs a lot of the things she does, she just needs them.
It would help to compliment her on how good she looks in the new outfits when you see her in each of them, even if it isn't on this trip. (Even if the outfit is not very attractive, SHE looks good in it, don't mention anything negative.)
Remember this, even if you have to put a small reminder on your loading bench or in your gun safe. The next time she questions your need for another gun or any related accessories, simply explain that your needs are as almost as important as hers, remind her of how good she looked in that new outfit, then ask her how you look holding that new custom made beauty of a shootin' iron.
Good luck.
