I ordered my Prima in Pearl White on [...].  It took almost 2 weeks for me to received them.  As some reviewer mentioned, the Pearl White is NOT "Pearl-White".  Some said it's more of a gray, some said aluminum, but the real color is more like Plaster White.  Dull, non-reflective, Plaster-White with a hint of stony grey (just look at the plaster in your wall).

On their website, it currently show 4 colors: Pearl (White), Celery (Light Green), Sea Foam (Aqua), and Lavender (Light Purple).  From what you see on the [...], it seems all four colors has a hint of "pearl" in them.  Even when you enlarge each and every photo of each color, it shows a hint of shiny "pearl" in all four of them.  But in reality, they all are dull, pastel, pasty color.

I was looking for a pair of cheap ballet flat where I can wear with any tops, I was a bit disappointed with the color, BUT, it is still easier to match tops with a Plaster-Stony-White then dull-pasty green, aqua or purple (personal opinion).  So I'm keeping these ([...])

I ordered a size 7, which is what I normally wear in all shoes.  The fit was fine for me (as long as they don't shrink - crossing my fingers now), the heel is not as low as the side (as in the width). If you run in them, there is a high possibility that you might fall flat on your face.

I've only had them for a couple of hours, so I haven't had a chance to test the comfort level.  I post an update after I wear them for a couple of weeks.
