hello everyone. im taking a huge step by purchasing my first LV bag, but im torn between the keepall 50 and 55 ush:. on the one hand, i think 50 is a good size for me, because im 5'6" and the 55 looks a bit big on me at first glance. but at the same time, im thinking the 55 may be the most popular since some only come in the 55 size, and it probably looks nicer when its not completely full and there's some creases in the bag when it dips down in the middle when using the shoulder strap. what do you think ? any opinion would be greatly appreciated. thank you!
