Windows are notoriously overlooked in interiors — seen as all function, no form. But the truth of the matter is that they are so much more than that. Whether roller shade or layered drapery, your choice of covering can seriously elevate your space... or seriously drag it down if you opt for an outdated window treatment.
It's not necessarily that curtains are out of style, but certainly some styles are. And not paying enough attention to it? That's never a good look. "The window is a vertical canvas that can frame a view, add grandeur, texture, and complement the architecture," explains interior designer Alison Downey of DOWNEY. "Homeowners are now realizing how much character and warmth this element can bring, and designers are heeding the call."
It's 2025. Don't settle on a curtain or blind that is anything less than fabulous. Here are four outdated modern window treatments to avoid in 2025, and what designers would replace them with.
1. The 'No-Treatment' Treatment

The number one way to show you aren't up to speed on the latest curtain trends? Overlooking your windows altogether.
"Windows are having a renaissance in today's interior design trends, but too often, they’re still overlooked," says Alison Downey. And leaving your windows bare can often be a fast track to boredom.
"We work extensively in the Hamptons, and I’m always surprised by the absence of attention given to the windows in these grand, meticulously built homes," she adds. Solar shades alone just don't cut it.
Instead, Alison likes to take the opposite approach. Layered drapery combines texture, form, and function to create subtle drama in a space. And while heavy materials and fabrics can be beautiful in the right space, this look is easiest done with light materials like linen.
Try a double rod curtain idea or combine different window treatment styles. For example, Alison recommends "a textured Roman shade paired with an outside-mount ripplefold sheer drape, installed above the window frame, on a beautiful track."
"This combination instantly adds height, depth, and visual richness to a room," she says.
This ultra-sheer style of curtain from H&M is only £25 and the perfect piece for layering curtains.
2. Roller Shades

"I am ready to see fewer roller shades in residential projects," says Los Angeles-based interior designer Coco Greenblum.
While it's a practical type of blind, roller shades often feel commercial and cold in a home. "The material is limited by the mechanism, which requires a specific thickness and weave, leaving little room for warmth or texture," adds Coco.
And although it shares a similar mechanism, the Roman shade is still a definite 'yes' in 2025. "Relaxed Roman shades come up in my designs more often than not," says Coco. "They strike a perfect balance, neither too traditional nor too contemporary, while adding a layer of softness that complements a variety of interiors."
This relaxed Roman shade gives a chic bistro-style aesthetic while still feeling completely timeless.
3. Eyelet Curtains

Next up on the interior design chopping block? Eyelet, or grommet, curtains — you know, the ones with the metal ring at the top for the curtain rod to go through. Interior designer Anna Kroesser of Kroesser + Strat Design says, "We’d love to never see a grommet curtain again."
"The grommets are distracting and don’t give off an elevated feel to the space," she adds. And while these are typically available ready-made and at affordable prices, Anna says, "In 20205, there are so many other options out there that don’t need to be custom."
So don't go for eyelet curtains just because they're accessible. Stepping up your style game doesn't mean you have to drastically change your go-to for where to buy curtains. "When shopping retail, back tab options deliver a more custom look without the price tag," adds Anna. "We also love a fabric roman shade; they’re functional, but the fabric gives another layer of texture without overwhelming the space."
Back tab curtains bring a cleaner, more sophisticated aesthetic to a room.
4. Matchy-Matchy Cornice Boards

Interior designer, Yena Jung of By Yena Designs, says cornice boards (also known as pelmets) are another outdated window treatment in 2025. "I am simply tired of seeing a cornice board that matches the fabric of the curtains," she says.
There are other ways to make a floor-to-ceiling drape look great, and the cornice board often "seems overly contrived and takes away from the beautiful and intricate trim around a window," she adds. (Though we've seen some modern pelmet ideas that still work.)
If you are lucky enough to have decorative plasterwork or original crown molding in your home, you don't want to hide that behind a stiff board of fabric. Instead, Yena says, "Opt for floor-to-ceiling draping or any inset treatment that can be added as a complement to the overall design of the room."
In fact, having all your window treatments match in general is a bit dated in 2025. Instead, Yena recommends, "Roman shades that are inset into the window frame, and then add floor-to-ceiling drapery in a complementary look or design. This makes the entire room feel finished — you get a little drama from the drapes, but a relaxed Roman shade can look so comfortable and welcoming."
This streamlined, jute-effect Roman shade fits under the window frame, making it easy to pair with another layer of floor-to-ceiling curtains.
It’s a missed opportunity when windows aren’t given the attention they deserve. Once you've landed on a style, you can play with things like color and material. Just make sure to steer clear of any curtain colors going out of style after all this hard work.
