Fake eyelashes a makeup artist put on me for a photoshoot - couldn't blink they were so heavy
Individual lashes create a more natural look, and are normally placed between the natural lashes for a more defined look. Personally I hate wearing these eyelashes because its a very tedious job to place them but if your looking for a natural look I would recommend these.
For a dramatic effect consider buying strip lashes which are applied with glue/or stick on. Try and opt for the lashes that are appiled with glue because i found the ones that are stick on usually end up falling off if you are going out/going to be moving around alot.
One of the hardest set of fake eyelashes to get on the market, however they exist and create a both natural and dramatic effect. These lashes are speficially designed to direct to the corner of the eye.
