You can change your recessed light to a gimbal housing type of recessed light and aim it at the mirror to bounce light off of the mirror and onto you to avoid shadows. You can then add any another type of decorative lighting to this like sconces or pendants.

Sconces are supposed to be best.

I love the light provided by two sconces. I look years younger in the two baths that have side sconces than I do in the one with over the mirror ones.

I think a dozen will make me look older :) just buy two.

If you really want the best lighting conditions for makeup, get a mirror or medicine cabinet with built in light strips at a kelvin that is close to sunlight. Next best is sconces to the sides of a mirror. But if you put them really far apart (like only two sconces on either side of one long mirror over your long vanity), that still makes it hard to do makeup

You'll need a light in the middle of a counter that long, so I'd go with tall-ish, thin pendants.

Do NOT put gimbal lights that bounce light off the mirror onto your face! Why not? Because you'd be looking right into the reflection of the bulb itself. It's simple physics: The angle of incidence equals the angle of reflection. You'll be blinded by the glare of the bulbs.

Thank you all for the suggestions. We are building a house and are trying to correct the mistakes we made with our current one. LOVE our master bath and would do it all again the same way, except for the lighting. I will go with sconces that flank each mirror. Our next design dilemma is the TV placement. Learning that open concepts can be problematic. Not enough wall space for things. We have no place to put a TV (not a big deal to me; huge one for my husband). Two options -- mount it above the mantle of our stone fireplace or have it drop from the ceiling with the push of a button. Not sure how the latter would look with a coffered ceiling. Sigh.
