Ashley Olsen’s Walk in the Woods With a Machete

A rare photograph of a designer seldom seen or heard from has sent the internet into a tizzy.

Last week, Ashley Olsen swapped city sidewalks, single-use Starbucks cups and oversize bags for evergreens, a glass containing some amber liquid and a machete. Her signature layers remained intact. In a photograph posted by her boyfriend, Louis Eisner, as an Instagram story, Ms. Olsen strides through an unidentified forest (possibly in the Pacific Northwest, if another recent photo is any indicator) wearing loose white pants, a white shirt tied around her waist, a white sweatshirt hiked up to reveal an arm, and black Yeezys. The photo — a highly unusual upload from Mr. Eisner, whose grid contains no photos of Ms. Olsen, and a rare image of a designer known for being, as her sister Mary-Kate put it recently, “discreet” — set off a flurry of excitement on social media, where it was widely deemed “a mood,” as well as “a sexuality,” “a summer vibe” and “a spirit animal.” It also inspired several artistic interpretations.
