I just bought a pair of iron hearts. Cannot return them. Pants are 1.5 inches to wide at the waste but the length is perfect. How should I shrink the pants without effecting the length?

Thanks.

@Alex thank you. Should I wash it @ 30 and then use a drier for :20 min etc? Is this the process?

In ordered an XXL. XL fits a little tight but leaves no room for shrinkage if and when I wash it. Does anyone have any suggestions on how to deal with an XXL that will be bigger across the chest and longer in the arms in order to get a better fit?
