The humble slip skirt, first made famous by Réalisation Par back in 2018, has seen a revival on the streets of London in 2025, but with a twist. What began as a delicate bias-cut satin piece favored by Instagram influencers has evolved over the years, and this summer, the slip skirt is getting a romantic, vintage-inspired update that’s quickly becoming the go-to trend in London.

A Look Back at the Slip Skirt Phenomenon

Flashback to the late 2010s, when the slip skirt was practically ubiquitous, thanks in part to Réalisation Par’s highly sought-after silky leopard-print midi. Soon after, retailers jumped on the bandwagon, replicating the design in various colors, with Topshop’s Oxford Circus location being flooded with them. The silhouette was simple: an elasticated waistband, a bias cut, and a hem that usually hit just below the knee. It became the go-to piece for a laid-back yet elegant look that could be dressed up or down.

Fast-forward to 2025, and the slip skirt has transformed from a one-size-fits-all style into something far more refined and nuanced. While the essence of the slip skirt remains—flowing fabric, minimalism, and a hint of sensuality—this year’s iteration takes a cue from vintage lingerie and romantic undergarments.

Underwear-as-Outerwear, But With a Vintage Twist

Underwear-as-outerwear has long been a theme on the fashion runways, but for Spring/Summer 2025, it’s less about edgy, barely-there looks and more about embracing a softer, more nostalgic approach. Think romantic lingerie pieces you might stumble upon in a French flea market or tucked away in Portobello Road Market. These are the types of undergarments that your grandmother might have once worn—frilly briefs, white cotton nighties, and embroidered tights that would have once remained hidden beneath a floral tea dress and homespun cardigan.

The idea is no longer about exposing too much skin but rather about showcasing a kind of sweet, whimsical femininity. Enter the slip skirt, reimagined in silk and lace, designed to be worn as outerwear and to be seen in full daylight. It’s an invitation to embrace something delicate and nostalgic, and it’s quickly becoming one of the most coveted styles for the warmer months in 2025.

The Evolution of the Slip Skirt

In 2018, the slip skirt was characterized by its classic, streamlined silhouette—elasticated waistbands, bias cuts, and midi lengths. But in 2025, slip skirts have become more varied and dynamic. From flowing, high-low hems to the sleek, fitted ‘90s mini skirts reminiscent of Rachel Green’s iconic dress in Friends, the slip skirt is no longer confined to one style. The key differentiator now is the delicate lace detailing, which adds a touch of vintage charm to every piece.

Designs from Dries van Noten’s SS25 collection showcase fluid, draped slip skirts with varying hem lengths, blending femininity with artistic flair. Meanwhile, The Row’s latest collection nods to simpler, yet equally chic slip skirts with lace inserts and tonal color palettes, creating a more refined take on the trend.

The lace trim is becoming the signature feature, whether it’s in a contrasting color or a tonal match. This added detail gives the skirt an almost ethereal, antique quality—perfect for the modern woman who enjoys the elegance of vintage fashion without sacrificing modern style sensibilities.

How to Update Your Slip Skirt for 2025

If your slip skirt collection is feeling a little dated, don’t worry—there’s an easy fix. Adding a lace trim to the hemline of your existing skirts can instantly bring them up to date with this year’s look. Whether it’s a soft cream lace or a contrasting black trim, this addition will bring a timeless, romantic flair to your wardrobe. The lace detail works across various styles, whether you opt for a midi skirt with a high-low hem or a more fitted mini skirt.

The beauty of the slip skirt in 2025 is its versatility. You can pair it with a simple white blouse for an understated look, or layer it with a vintage-inspired knit for a softer, more textured outfit. It’s a piece that can easily transition from day to night, making it one of the most adaptable trends of the season.

Why Everyone’s Wearing It in London

London’s fashion-forward crowd has always been quick to adopt global trends, but what makes this year’s slip skirt so desirable is its ability to merge nostalgia with modernity. The lace details, the vintage lingerie inspiration, and the flowy yet elegant silhouette offer a balance between romanticism and effortless style. It’s an accessible luxury that feels both feminine and practical, perfect for navigating London’s unpredictable summer weather.

Whether you’re brunching in Notting Hill, strolling through Soho, or grabbing a coffee by the Thames, the slip skirt is quickly becoming a summer essential in London. It’s a piece that evokes a sense of calm and grace, while still feeling thoroughly contemporary—a look that embodies a quiet, sophisticated form of rebellion against the chaos of fast fashion.

So, as the temperatures rise, expect to see more and more Londoners embracing the slip skirt trend, with delicate lace hems catching the sunlight, and the vintage-inspired fabric flowing gracefully in the breeze. This summer, it’s all about soft elegance, subtle sensuality, and a nod to the past, making the slip skirt an essential item in any wardrobe.
