I don't like leather-lined bags.

I know, they're super luxurious but it kills me how scratched up mine always end up. I'm so OCD about that stuff... I prefer bags with carefree canvas lining. For this reason I am more attracted to seasonal flap bags that look classic-ish than actual classic flaps.
Re: investment bags, I'm one who likes to buy "investment bags." It's not because I can't afford them... it's because I get tired of bags, fast, and being able to sell it without taking a huge loss makes me feel a lot better about the occasional impulsive shopping. I'm under no pretenses that they are actual investments like stocks or real estate though.
