I made Pieter's costume based a bit on that design.
Ever consider making one yourself?
I can not sew, but even I managed to pull it off.
I used white sheets to make it.

Maybe not exactly what you're after:
Amazon.com: Adult Mad Scientist Halloween...
edit: I see Terra beat me to that one...

Pricey..."the Betty" certainly fits the look.

Don't know if they import...

Might be usefull in your search: Some places call this style a "Howie Lab Coat"


Perhaps thinking outside the box here...what about a Chef's coat?

The reason I knew about the perfect costume is because they didn't make it two years ago and I had to make it myself (UGH!). But, it was SUPER easy to make. Get a white mens robe and wear it back to front. Sew buttons where you see it on the costume picture and draw a fine line where the seam would be and sew a zig zag stitch to give the appearance of a seam. Then find a wide black belt. Walla, you are done!

thanks lancekik, but id rather not spend so much. it would look a hell of a lot better, but id rather put money towards something else and make one.

Dude...I friggin' hate all those sexy nurse costumes. hah hah.

I say every single year "Halloween is not about the sexy, it's about the SCARY." I live in a college town though so the sorrostitutes line up the dressing rooms to try on sexy-this and sexy-that costumes. I'm checking out the knives and machetes and whatnot. hah hah.

On the labcoat front...you could get a long sleeve scrub top, the add a mock turtleneck collar around it.

I've been trying FOREVER to find a black lab coat that's not polyester. I work in a lab and really want one but can't ever seem to find anything except white in a regular type labcoat. Talk about drive me up the wall.

I'm a little late, but....
