Kim Kardashian is typically known for being married to Kanye West, being one of the stars of E!'s "Keeping Up With The Kardashians," or her self-proclaimed title of selfie queen.

With her fashion forward outfits, she's normally seen bearing that amazing cleavage in plunging necklines. Now, Kim Kardashian West is revealing her secret for those perky breasts sans the bra.

In fact, Mrs. Kanye West even shared the tip with little sister Kylie Jenner - which the 17-year-old actually used on her outfit for the Sugar Factory opening in Miami just a few days ago.

Glamour also said that reports claim Kylie had Kim to thank for perfecting the "gravity-defying cleavage."

"Kim called friends to brag about how her perfect duct-tape instructions kept everything in place," an insider tells Page Six.

Celebrity stylist Anita Patrickson says, "A lot of people tape their boobs up. People have definitely done it with duct tape."

Patrickson explains the process: "If you're having one of those Kim K. dresses with two bands on either side [of the breasts], you want to stick the tape over the nipple, pull it up, and then stick it to the side. You're basically giving yourself a lift."

However, duct tape isn't the only supply store product that can be used. Other alternatives include the Breast Lift Tape by Hollywood Fashion Secrets, a company that offers products for "wardrobe fixers."

In fact, the Breast Lift Tape is a great option since the adhesive is hypoallergenic, and can be used by ladies with cup sizes from A to D.

The Ultimate Bra Guide also suggests using surgical tape or sports strapping tape. Unfortunately, the two kinds of type only work with apparel that are thick and non-see through.

When using duct tape, though, the website recommends using products that aren't "super sticky." But for those with sensitive skin, its best to avoid the duct tape route.
