Mom asking for "" for her birthday?

So my mom's birthday is soon, i heard her say that she wants a jacket to wear to work and to cover up from the cold. I'm uming something cly and nice. We are a very strict christian family and do not support fur coats and such. My problem is im a guy and i don't know whats "fashionable" at the moment for ladies age 40 and up. I know plenty people wear those ugg boots but i think she already has a pair. I overheard a conversation when she was talking to my dad about getting "" but i have no clue what it is and my dad for some reason laughed and said he couldn't help her.. i didnt ask her what it was because i want to surprise her with it if i can afford it, im guessing its some kind of high-priced high-cl coat?
