The line initially made its debut in 2019 but quickly sold out and has since has had a waitlist of more than 250,000 people and over 4,000 five-star reviews.
Including a size-inclusive range of bras, underwear and other underpinnings, the line is back with four new styles as well as colors -- making it the brand's largest restock.
Of the new styles, the Fits Everybody collection is expanding to include tees, leggings and slip dresses in sizes XXS - 4X.
These pieces will also be available in three new seasonal hues including soft muted whites, blues and greens.
The texture of each item was created to be soft, stretchy and supportive.
SKIMS shared campaign images on Instagram featuring shots by Vanessa Beecroft and Donna Trope that showcase a lineup of diverse models of all different shapes, sizes and ethnicities wearing the latest restock.
One standout from the latest additions is the Fits Everybody Slip Dress. "A buttery soft mini dress that hugs your curves," the brand notes on its website. "Form-fitting and lightweight, this style is perfect to wear under other dresses as second-skin lining."
It also features a wide scoop neckline and adjustable straps that make it easy to layer under clothing.
In addition to the restock, the brand also announced that its popular Slide slipper was also making a comeback.
"Head to toe - The Slide is @kimkardashian's go-to for off-duty coziness," the apparel brand shared in a post alongside Kim wearing the slipper in its Smoke color.
As pieces tend to sell fast now, shop now ... or maybe never.
