Shannon, this is a tough one!
First off, I LOVE you in white! You are going to love wearing more of it.
Secondly, I am not against stop-gap purchases or "try-out" purchases, as you know. I think they can be a great way to test the waters.
Third, this is a fun jacket, and looks pretty darned good on you with both jeans and a dress.
Fourth, practicalities are relevant -- the fact that it is washable is a plus, for sure.
Fifth, it's a good price.
Now for the "buts."
I am like Sveta. I have tried and tried, but I cannot wear faux leather. It feels sticky, icky, hot, unbreathable (even with panels like so) and if there is even a whiff of humidity in the air, just plain yukky. Whereas leather breathes and feels gorgeous against the hand and skin.
I am not a fan of what appears to be the crinkly texture on this. That might fall out a bit with wear as you "heat" the jacket with the warmth of your body.
In the end, only you can say if this is the right addition to your closet. If it suits your style, your shape, your pocketbook, and your goals, AND the comfort factor is there for you, I say yay.
For myself, it would be ticking a whole lot of boxes but not the comfort boxes. Now, if it were a faux leather VEST, that I might try, but for a jacket, I'm either going fabric or real leather.
By the way, I have a cropped white denim jacket that I do enjoy a lot. I don't think they are exactly substitutes, but perhaps similar enough that you would feel it was duplication. However, if you found yourself wearing one constantly and the other not at all, it would be easy to consign or donate the unused one. Or offer to a YLF friend.
One final point. Remember how I tried a leather moto in the fall, and ended up returning it (due to fit) and instead bought a waxed denim moto?
Well, I know. Waxed denim is not faux leather. But there is something a bit similar in the "hand" of these materials.
Guess what? I wore that waxed denim moto a grand total of about 6 or 8 times. And I just donated it to my stepdaughter. I HATED the way it felt, hated the way it LOOKED, even. It just could not compare to the feeling of leather. In the end I decided, for me, it's a proper fabric or it's leather -- no in-betweens. The waxed thing felt too cheap.
