Coconut Girl (also known as Malibu Barbie and Key West Kitten ) is a Coquette subtype centered around the Nymphet interpretation of tropical beaches typically associated with the Florida Keys, Hawaii, and Caribbean islands. It creates an atmosphere that expresses the femininity and youth associated with young women vacationing during the summertime.

The aesthetic has multiple interpretations; while in the beginning, it was known among the Nymphet community, it later gained more mainstream appeal and was connected to other beach-related aesthetics such as surf culture . Because of this, visuals may differ and is connected to the practice of mass-tagging.

The aesthetic stems from early 2000s girly summer tourist culture and is influenced from pictures on Pinterest illustrating those times. It then began to grow popular on TikTok by young women who have developed a fascination with the unreleased songs of Lizzie Grant (Lana Del Rey), specifically the songs "Mermaid Motel," "Hawaiian Tropic", "St. Tropez," and "Wayamaya."

The last song is largely the most frequently played in Coconut Girl TikToks, and its imagery largely codified the aesthetic; ukelele, Lana's girlish and dreamy tone, and lyrics centering around vacationing in the upper-class areas of Hawaii are traits that can be easily translated into visuals.

Like other aesthetic TikToks, these content creators play the songs while rapidly showing images of Coconut Girl aesthetics.

The ideology around the Coconut Girl aesthetic comes from the followers of the aesthetic, who are mostly young women in their teens and twenties. Feminine sensuality and youth is strongly associated with the aesthetic. However, anyone of any age or gender can participate in Coconut Girl. The most important part of the aesthetic is the mindset of relaxation and fun.

Much of the imagery associated with this originated from the Surf Crush trend of the early 2000s, combined with the brightly colored and plastic Tween culture of the time period. And due to the influence of Lana Del Rey/Lizzie Grant, Vintage Americana motifs inspired by beach culture are common. Nautical and Tropical imagery is also seen as well.

Popular Coconut Girl fashion opts for fashion from and inspired by clothing and brands that were popular in the early 2000s among the teens and tweens of the time. Some of these brands can include: Roxy, Billabong, Delia*s, and Claire's.

The name "Coconut Girl" has faced criticism because "coconut" serves as a racial pejorative within some communities of color, historically used to describe a person who is "brown on the outside, white on the inside." Consequently, many users prefer the alternative term "Key West Kitten" to avoid these connotations.
