i need help!

i need help! i'm having a difficult time trying to make collard shirts. i attempted a deep v-cut which went fine, but everytime i go for an oval shape, the collar ruffles instead of the smooth line you normally see on shirts and things.

do any of you know where i can find a tutorial on how to make proper collars? i can't seem to find any.

EDIT - sorry, i should have specified. by collar, i just meant the regular lining of a tshirt, around the neck, as in this picture.
