“Express Yourself,” indeed.

Madonna was the guest of honor at a glitzy Saint Laurent bash celebrating its “S.e.x by Madonna” exhibition, which commemorates the new edition of the Queen of Pop’s groundbreaking 1992 book “S.e.x,” on Thursday.

And true to form, the 64-year-old music icon was the most daring dresser in attendance, clad in a plunging black lace bustier, fishnets and a black double-breasted tuxedo jacket ($3,390) from the fashion brand, even accessorizing her pantsless look with a riding crop.

The “Material Girl” singer wore her customary layers of silver and diamond jewelry, although she appeared to skip the infamous vibrator necklace she’s been sporting recently.

The mom of six, who’s no stranger to wearing lingerie as outerwear, braided her long red extensions into Pippi Longstocking-style pigtails and continued to rock bleached brows along with one of her go-to diamond grills.

The Grammy winner’s 26-year-old daughter, Lourdes, coordinated with her mom in a black crop top and maxi skirt with a thigh-baring slit, plus a gleaming cross necklace.

Madonna’s ex-boyfriend Tony Ward, who appears in the book’s soft-core pornographic photographs, also hit the Miami party.

The exhibition is open from November 29 through December 4 at the beachfront of 17th Street to honor the re-release.

Hailey Bieber and Zoë Kravitz also hit the star-studded Basel bash.

In October, Madonna spoke out about how the once-controversial book has paved the way for female musicians.

After its release, Madonna said she “spent the next few years being interviewed by narrow minded people who tried to shame [her] for empowering [herself] as a Woman.”

“Now Cardi B can sing about her WAP. Kim Kardashian can grace the cover of any magazine with her naked ass and Miley Cyrus can come in like a wrecking ball,” Madonna said.
