Kim Kardashian -- Making Up with Her Costs a Grand!!!

Kim Kardashian will give you a foundation for life ... for a thousand bucks.

Get this ... she's giving a class on makeup ... not at a junior college, not at a beauty school. Kim is filling the 3,000 seat Pasadena Civic Center auditorium for a 4 1/2 hour class on July 25.

Her contribution to the class is basically sitting in a chair while makeup guru Mario Dedvanovic does his thing on her.

The best seats go for $1k, but there's a bonus. You get a pic with the finished product.

As for the cheap seats ... they ain't that cheap -- $500.

Kim K ... the great concealer.
