Lea Michelle (5'2"). I love her character's style on Glee and I never would have know how small she is.
Reese Witherspoon (5'1.5"). I honestly never would have known. Even in flats she just doesn't come off as a shorty to me. Reese definitely provides style inspiration for me!
After going through loads of pics I have concluded that if I don't want to look short I should probably (1) live in high heels, (2) wear dresses that show the knees, (3) become ultra ultra-thin, or (4) screw it all and just hang out with other shorties!
