Bad or good idea to wear real fur jacket?

So my grandma came to me today and gave me a white (REAL) mink coat. She’s had it for 30 years, and says it’s too small for her, so it’s either mine or straight to Goodwill it goes.

Looks about like this but not as perfectly white: http://i01.i.aliimg.com/wsphoto/v0/1998592389_1/Wholesale-Autumn-And-Winter-Coat-font-b-Women-b-font-Fur-Coat-White-Fur-Collar-Long.jpg

I have mixed feelings. On the one hand, I like it. I keep picturing myself in pinup diva hair, red lipstick, and boots lol. And it’s really warm….

On the other hand, I am aware that a lot of people have serious problems with real fur coats. To be honest, I can barely tell the difference between real vs a good fake just by looking at it (feels different though) and I don’t know if other people would assume one way or the other upon first glance. I have faux fur items, but I feel like they look clearly fake. I wouldn’t buy a brand new fur coat (overpriced and I’d feel a little guilty), but since it’s recycled/vintage, I feel like this is a different situation.

I have a leather jacket, so I suppose this shouldn’t be any different, but it seems like a totally different stigma when it comes to fur.

What are your thoughts? Should I keep it and rock it or let her give it to goodwill?
