I'm just going to have them altered, don't want to risk it
That's the best decision. When you shrink wool, it seldom if ever shrinks evenly. I've seen sweaters that accidentally got mixed in with the regular laundry and shrunk about 30 percent in width and about 70 percent in length. It was my wifes and after it came out of the dryer, it would have fit a 12 year old like a tube top with sleeves.
FYI, for those of you in the normal size ranges, I just bought two pairs of VERY nice wool lined bibs from sportsman's guide. They were under military surplus as I think Italian navy wool lined bibs. These things are amazingly well made. Kinda remind me of Filson but not the tin cloth. More like the softer stuff they sell but I can't recall the name. Very tight weave though. The lining is like the old brown army blankets and they are built VERY well. Only problem is, the size XL fits me in the legs and but but not up over the belly and chest. I'm 6'2" and 270 so... usually wear a 2x but I was hoping for a baggy fit item that I could squeeze into. Oh, and get this! Only $17.97 and they're brand new, never issued.
