The geniuses behind Net-a-Porter launched the lower-priced sister site, theOutnet, earlier this year (to much budget-saving fanfare).

Now, theOutnet will be launching its first online clearance pop-up sale starting tomorrow at 10 a.m. ET.

Expect some serious bargains -- think 75-85 percent off labels like Fendi, DKNY and Jimmy Choo.

We had a preview of the some of the chic sale selections, which included a black and gold Jimmy Choo clutch that normally retails for $1,995, but will be marked down to $399. (A step closer to prices for the upcoming H&M/Jimmy Choo collaboration!)

This sweet, petal pink Miu Miu dress (right) was originally tagged at $760, but will sell for just $190 during the sale. We want it!

The clearance prices will be offered until Sunday, August 9 at midnight ET, but with discounts this steep, we suggest logging on early.

Don't say we didn't warn you!
