Well, she likes the sweater, and it fits, so....
I have this t-shirt my dad got for me on a trip in the 80's...I still wear it. Not OUT, but it's part of a night at home outfit. Ain't nothing wrong with that!
(it's awful too, it's light yellow with some 80's logo from a camp vacation he took w/ friends, I think there's even a brown bear on it. Don't judge, that shit is so worn in and still in one piece. I may go find it now! Squee, cozy clothes are THE best!)
My son is 6'2" and weighs all of 155 pounds so he is too skinny to steal clothes from, although he does have a DMB shirt that I have attempted to take.
Once he hit his teens, the clothes were big enough for W, and after our son outgrew 'em, she took 'em over. They were a lot better made than most women's clothing, so she was able to wear the stuff for many years. It just dawned on me last night that some of the clothes are 25+ years old and still going strong.
It was pretty big... like, for a 7 year old.
