chacha: You can view actual people wearing circle lenses here:

pinkiipromise: Yeah, it sucks that the colors are limited for toric lenses. But there are brands out there that carry toric circle lenses in more colors.
Emiey: These enlarge the look of your irises...not your eyes

Sort of like the dolly-eyed look.
loveQQT: Never bought from that site before but the prices are too high...
And as a side note...it's strongly encouraged to get your eyes checked to get your correct prescription (if any) before getting these lenses. And have eye drops with you all the time. Due to the bigger diameter your eyes get dry more easily as opposed to regular lenses and you shouldn't wear them for more than 6 or 8 hours at a time.
