I'm still a makeup n00b and have been practicing playing around with false lashes. I still gravitate towards the more natural looking lashes. Recently I went to a makeup trial and the lashes the MUA used are super defined and flared at the wing giving a very cat eye look. Excused the crooked or partially glued weirdness and derpy faces (that's just my face) ... I'm still learning, I did read a blogpost where they apply the glue to directly on the eye instead of the lash... I might try that next time since positioning is the biggest @#$%!
I always find it more helpful when I see the lash actually on a person.
I really love the dolly wink series but trim them a lot since I'm not really into the full on "dolly" look. They're pricey but look so nice! The Diamond Lash Little Wing series is a great cheaper alternative.
