And despite the plethora of options available online, it took Topshop's silk slip just three hours to sell out online.
Brought out originally in chocolate black, and rust (the latter two of which have been restocked twice, and the black that will continue to be restocked for the next few months), it was then launched in four new colours in November and four new prints - spotted, tie-dye and two variations of tiger-print.
And why change a winning formula?
While in a neutral palette spanning pinks to whites and greys, which will be followed by soft apricot, pink and coral for Feb, it's our sneak peek at the summer incarnation that we can't get enough of.
Dropping mid-march, two floral printed pieces have been revealed in fuchsia pink and mint green. And we are counting. Down. The. Days.
Speaking of the skirt style's unprecedented success, Toni Purdie (Head of Design at Topshop) said: "The satin slip is the must have item for the season as it's super versatile and ready for any occasion as the ankle grazing silhouette is the perfect length to dress up or down, and it will take you from day to night with ease."
"It's been about the midi length dress for so long, its time to mix it up with some separates and get more mileage with your favourite wardrobe staples."
