No BV qualifies as an investment if you think you can resell for more than you pay for it. Some Hermes, certain special Chanel pieces and Judith Leiber and possibly special edition LV are probably the only bags that you could make money on and even then, it’s high risk.
On the other hand, if you mean an investment piece to use long term as a classic and will not look dated then it’s anyone’s guess but if YOU love the bag, go for it.
