I think it is not a question of "need" but a question of "desires". Do we "need" a $1,000 handbag, etc, etc.
The thread was really about the styles that celebs choose when wearing their furs rather than whether people themselves believe in them or not, etc.
I suppose celebs travel an awful lot in which case they need / want wardrobes for every climate.
Anyway, I have just found another I really like worn by J Lo. I believe this is mink and I like they way she wears it with similar colors. Single tone / colors work better than anything when pulled off properly IMO.
