Rachel Cook Shares Sultry 'Casual Friday' Video in Sheer Corset

Rachel Cook, who has 3.7 million followers on Instagram, shared a video Friday wearing a sheer black cropped corset and thigh-skimming miniskirt while dancing to romantic music. She described the ensemble as “casual Friday attire” in the caption, which included a winking emoji.

The corset and styling details

Cook’s outfit featured a candy-pink, ribbed corset with a plunging neckline, tiny rose motifs, and a low back. The structured piece appeared semi-sheer, revealing her muscular back and toned abs. Red and green accents from the floral design complemented the look, while a cross necklace emphasized her cleavage.

She styled the outfit with warm, girly makeup—pink blush, pink lipstick, and highlighter—and wore her hair down. A hanging sash and strappy black heels completed the ensemble. In one moment, she tugged down her low-rise skirt, briefly revealing pink briefs.

Home bar setting and July reference

The video was filmed in a home bar setting, echoing a still photo Cook had posted in mid-July. That earlier image also showed her in the same corset and miniskirt, posing as if inviting fans to join her. The July post served as the visual foundation for the Friday video release.

Earlier bikini and headscarf post

In a separate X repost, Cook appeared in a skimpy pink bikini—halter top and cheeky briefs—leaning forward over a farmhouse table with a fruit bowl and water. She wore a gingham headscarf and showcased her pert backside and toned waistline.

Fans revisit 2022 wedding photo

Online discussion extended beyond the latest posts, with fans revisiting Cook’s wedding photo from four years ago. One Reddit user wrote: “Her getting married is really going to complicate my future relationship with her……”, a comment liked by more than 300 users. Another added: “Ooooooh Nooooo! There goes all our chances!” A third asked: “What’s the over under on how long they last?”
