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.
