I think all three looks are nice, but for a more every day look I would go for Michelle's.

i like Alexandra's make up the best!

I do this fairly often, but not quite as extreme. I layer it over a fat shadow stick so it doesn't come off and smudge it out. If I have some green in the shadow I used on my upper lid, I'll put a bit of green on my lower lid. Or blue or brown or whatever the colors I am wearing that day. But I don't do it anywhere near as thick as the way the women above are wearing it. More like a bit of a fatter liner. A darker one in the outer corners of my eyes, then the highlight color I've chosen in the middle third. Then a much lighter shadow in the inner corners of my eyes, with all of them kind of smudged together at their edges.

Brenda, you don't like the way I do my eye makeup? LOL Must drive you nuts every time you see me with it like that haha :-) I'll think of you from now on every time I do my eyes that way :-)

i always put a little bit of a light shimmery shadow under my eyes.

Sorry I'm not a fan of this look

i love using teal under my eyes. it really makes a neutral eye pop and adds an element of fun

love love love these looks.

I think it can look nice but it depends on the colours you use, and it looks better if its just a thin line like Tammy's. Personally, I would only use blue and purple but you could also use a one that enhances your eye colour. :)

I have to say I'm not a fan - eye shadow under the eye just looks dirty/sloppy to me - I prefer the heavily lined top lid look and just a touch of mascara on the bottom or very light touch of eyeliner. I do think it works better on some than others though - depends on your colouring and eye shape.

For smokey eyes, whatever colour I used as a shade in the eye crease, I use underneath my eyes. It gives eyes more contour rather than just the wet line and top eyelid shading. I use it for "natural" eyes sometimes, too. When I use browns, pale peaches, golds, etc. I often put it under my eyes to make them pop a little more. Shadows with sparkles or glimmer in it makes my eyes look a little more dressed up or whimsical. I, also, use light shades across the lower lash line to make my eyes lighter and bigger when I do pin-up style makeup.
