I pack DH's clothes, as I said upthread, because I am packing the whole suitcase in one go - we don't have separate bags.
So obviously I have no problem at all with husbands and wives doing things for each other, playing to their strengths, yadda, yadda.
But I am repeatedly
at all these tales of men who actually can't pack and just choose some random, inappropriate items to bring. I mean, really??!!
My 4 year old chooses her own clothes to pack, (though I put them in the suitcase, as I said before.) Even she knows, and has done for a while, what sort of clothes she needs to bring with her. Yes, she tries to sneak in a tutu, lots of necklaces and her ballet shoes, but she wouldn't put just those things in. She knows she also needs underwear, pjs, trousers, tops, hairbrush, toothbrush, jacket, swimming costume. Yes, we're not quite there on the right numbers of different clothes yet, but she's only 4. So I tell her, OK you need 7 pairs of pants and 7 pairs of socks, and then we count them out together. I can't imagine having to do the same for your DH 
I am totally flummoxed by the idea that a grown man wouldn't know what he needs.
