An arrow line appears shorter than a line of the same length with tails — Müller-Lyer illusion.
Experiment with arrows in clothing. For example, a V-shaped skirt or swimsuit will elongate the legs.
V-shaped collars and tops will vertically elongate the upper body.
You can apply eye makeup to visually increase them. 1
