I agree with others. Your need may be clothes, not luggage. I've gone overseas 2-3 months at a time, needing to show up dressed with a tie, and haven't checked a bag in the last 9 years. A 20-21 inch roll aboard with a trifold garment bag gets the job done. 1 suit, 1 navy blue sports jacket, 2-3 dress pants, a white and a blue shirt, and half a dozen ties. Lots of ways to mix and match. I try to bring an old piece or two that I'm willing to leave there so that I can buy something new to further spice it up.

I make sure that the clothing I bring is travel friendly. Not travel clothes, regular clothes, but some material wrinkles more than others. I never have to iron. The hot shower is all it needs.
