## The Slip, the Trouser, the Coat
The Slip, the Trouser, the Coat
Saint Laurent is doing three things this season, and they're all happening above the knee or below the hip. The middle — where trends usually live, where a blouse might signal intent — has gone quiet. What's left is a wardrobe built on endpoints: a bias-cut slip that reads like lingerie until you see the shoulder, a mid-rise tailored trouser that replaced the pooling hems of the last three years, and a coat so long it asks you to reconsider what outerwear actually does.
Anthony Vaccarello showed this formula in the autumn/winter 2024 collection, and it's held. The slip dress came out in black silk charmeuse, cut on the bias with enough weight to resist cling but not enough to structure. It moved like liquid, which is the point. But the shoulder seam sat exactly where a shoulder seam should sit — not dropped, not deconstructed, just placed. That one detail turned the piece from bedroom to evening without asking for jewellery or a blazer to legitimise it.
The trouser is where Saint Laurent made the sharper move. For three seasons, the house leaned into a low-slung, wide-leg silhouette that looked best on someone who didn't need to sit down. This season, the rise came up. Not high — this isn't Phoebe Philo at Céline — but mid, sitting just below the natural waist. The leg stayed straight, the break clean. The fabric is wool gabardine, not the fluid viscose blends that defined the previous run. It's a trouser that asks to be worn with a heel, which is a request the house hasn't made in a while.
The coat is doing the most work. Vaccarello showed it in camel wool, cut past the knee, sometimes to mid-calf, with a single-breasted closure and sleeves that don't taper. It's not a duster — the structure is there, the shoulder is built — but it's long enough to reframe everything underneath. You can wear it over the slip, over the trouser, over both. It becomes the silhouette. The coat isn't an addition; it's the read.
This isn't isolated to Saint Laurent. The Row showed a similar trouser in navy wool for spring 2024, paired with a slip in silk crêpe de chine. Totême's autumn collection leaned into the same coat length, though their version came in a softer shoulder and a double-breasted close. The Frankie Shop — closer to the accessible end of the market — has been running variations on this trouser for two seasons, and their slip dresses, though cut looser, are moving the same way. Even Khaite, which usually holds to a more American proportion, showed a mid-rise trouser in their pre-fall lineup.
What's consistent across all of them is the removal of the middle. The blouse, the knit, the shirt — they're still there, but they're not the story. The story is the slip or the coat, sometimes both, and the trouser that bridges them. It's a wardrobe that works in three pieces, which is either efficient or limiting depending on how you dress.
Saint Laurent's version has the advantage of legacy. The slip dress has been in the house's vocabulary since the Tom Ford years, though Ford's version sat tighter and shorter. The tailored trouser is Yves Saint Laurent's original contribution to womenswear, so any return to it feels like the house remembering what it does best. The coat is newer, but it's doing what Saint Laurent coats have always done: providing a frame that makes everything else look intentional.
The question is whether this holds past the next twelve months. The slip dress has been cycling in and out of relevance since the nineties, and it tends to last about eighteen months before it tips into costume. The trouser has better odds — mid-rise is a more sustainable proportion than low or high, and the straight leg doesn't date the way a wide leg does. The coat is the wildcard. It's a strong piece, but it's also a big ask. You need a certain amount of space — physical and metaphorical — to wear something that long without it wearing you.
For now, though, this is the clearest read Saint Laurent has offered in three seasons. The slip, the trouser, the coat. You can dress in this for the next year without second-guessing the proportions, which is more than most collections are offering right now.
