so, ive noticed on every single piece, you always use liner on the waterline, and shadow on the bottom lid. is there a reason for this besides you find it works for you? if tried it on me a couple of times, and i feel like color on the bottom lid just makes my eyes look too deeply set, or big bags or something, and the water line always smudges off after a bit.
When I don't have eyeliner or shadow underneath my eye, I look tired and my eyes look puffy. The black helps bring down the puff. The waterline always rubs off, but it stays just where the lashes start, so it keeps my eyes looking smoother.
