I see it a bit to large in the back, and a bit too short for wearring with pants to my like, thus shorter lengths are great for skirts and dresses.
Just wanted to add, I do have a white denim jacket (post YLF) which is a tad longer(to hip) but it's quite streamlined and really a good fit which I CANNOT LIVE WITHOUT from spring to fall! I keep it perfect crisp white, and use it mostly over dressier outfits to work, which I do want to lower the dressiness level-and/or raise it's trendyness(if that's making sense?). You can think wearring it instead of a crisp white jacket, which I do also have, but sometimes feel much too dressy and conventional for an everyday outfit to the office, and save it for more formal events. I am also wearring it today to my red linen midi, and ruffle front olive blouse, as it's a bit chilly today, but this white screams SPRING to mee, and feel fab, while adding a bit of warmth.
Also wear it casuals(sometimes), to skinny jeans, with longer tops, but then I really find it's longer length more flatterring...
So, I strongly encourage You to not give up on white denim jackets, as I find them very very usefull, and I'm sure there is one for you, either.
