well if you like more natural colors than i would suggest dipdown because blacktrack might be too much if you are going for more NATURAL! my friend like natural and her eyes are small so she prefers the dipdown... i like them all!
Well if you like the natural look I would definitely go with Dipdown. Blacktrack is awesome, but I don't wear it as much as Dipdown because I feel like it's just too much for me most of the time.
