Happy Lazy Girl Olympics! Today is the day when slackers across the country compete to make the most creative Halloween costume with the least amount of effort. Past winners have often included fake blood, animal ears, and zippered onesies.

The onesie (aka hootie pajamas), completed after much trial and error, looks like a costume but feels like pajamas, the ultimate lazy-girl style. And while she has virtually endless options, this is exactly how Rihanna chose to do it for Halloweekend 2024.

On October 30, the mogul celebrated All Saints' Day in Santa Monica with dinner at Giorgio Baldi. She appeared in a costume that can be put on and taken off, a costume that is sure to be copied all over again in the future. Covered from head to toe in leopard print, Rihanna wore a hooded onesie from her own brand Savage x Fenty.

Although her outfit required little effort, Rihanna accessorized to the highest degree. She layered tens of thousands worth of jewelry and accessories for the most expensive last-minute outfit in history.

As always, she was decked out in Bottega Veneta, wearing her signature $361 Shield sunglasses and $8,200 XL clutch (she paired the same bag with a gray sweater dress last week).

Her custom Gianvito Rossi pumps reflected the theme of the evening with their leopard print soles and glittery crystal straps. Meanwhile, two gold Marie Lichtenberg pendants, valued at $59,400, shone as jewelry around her neck. Hers was a custom-made version of the brand's “You Are the One” necklace, a fitting choice for the “You Da One” singer.

Procrastinators beware.
