Thank goodness for these! In the last few years there have been some amazing changes in the fibers that are used for making men's suits and tuxedos. We needed to find tuxedos for the wedding that were synthetic because of an allergy to wool on the groom's side. Come to find out, all of the nice tuxes that the big chain stores had were ALL wool! (there were some not-nice ones made of thick polyester).
Anyway, this might be something that you need to ask the groomsmen in the wedding - "Are you allergic to wool?"
