Because of my long torso - i can't buy those tops - entirely too short in front.
Even on this model - the short front sticks out like a maternity top. It may be the fault of the fabric chosen is a bit too "stiff" for that hi-lo style. It just doesn't hang properly.
Personally, I like a slight difference in length - front vs. back.
On almost all the knitted / crocheted tops/sweaters I make, I do a slightly longer back - with a sloping hemline. I think it's a more "graceful" look.
Graceful: : pleasing or attractive in line, proportion, or movement.
