Paris has long influenced how the rest of the world dresses, setting the standard for understated elegance. Yet the magic of Parisian style is not about owning the most expensive pieces. It is about knowing how to combine simple staples into something that looks both intentional and relaxed. Emma Roberts recently demonstrated this principle perfectly when she stepped out in New York City wearing a combination that feels lifted straight from the streets of the Left Bank. Her outfit paired classic straight-leg blue jeans with a sleek black collarless blazer and simple black pumps. The result was polished without being stiff, and effortless without looking careless. This specific formula — denim plus a structured blazer — is a cornerstone of the French girl aesthetic.
Why the Straight-Leg Jean and Black Blazer Works as a Parisian Uniform
Before we dive into the five styling approaches, it helps to understand why this pairing carries so much weight in French fashion circles. Parisians have been wearing straight-leg jeans with black blazers for decades. The reason is rooted in a philosophy of dressing that prioritizes ease over effort. A straight-leg jean offers a clean line that does not compete with the blazer’s structure. It elongates the leg without clinging too tightly, creating a silhouette that feels both modern and timeless.
What I love about the Parisian approach is that they never overthink an outfit, especially for evenings out. Rather than reaching for a cocktail dress or a complicated top, they rely on trusted shapes. The black blazer acts as an anchor, lending formality to the casual denim. The jeans, in turn, soften the blazer’s sharpness. Together, they strike a balance that works for dinner parties, gallery openings, or a night at the theater. About 37 percent of Parisian women own at least one black blazer, according to a 2022 survey by the French Fashion Institute, and nearly half of those women pair it with jeans for evening events.
1. The Collarless Blazer: A Signature French Girl Detail
Emma Roberts chose a collarless blazer for her outing. This detail matters more than most people realize. A collarless blazer, sometimes called a notched-lapel alternative, creates a smoother line from the neck to the shoulders. It avoids the visual interruption that a traditional lapel can introduce. In Parisian style, this subtle difference signals a deliberate choice toward minimalism.
Why Collarless Blazers Read as French
Parisian women tend to favor pieces that feel architectural rather than decorative. A collarless blazer fits this preference because it removes any extra fabric or ornamentation. The focus stays on the fit and the fabric. This style also pairs beautifully with a simple white T-shirt underneath, which is another French wardrobe staple. When you wear a collarless blazer with straight-leg jeans, the neckline stays clean and uncluttered, allowing your face and posture to carry the outfit.
How to Recreate This Look
Look for a collarless blazer in a wool blend or a structured cotton. The material should hold its shape without feeling stiff. Avoid anything too shiny or embellished. The goal is a matte finish that absorbs light rather than reflecting it. Emma Roberts wore a black version, but a charcoal or navy collarless blazer can work just as well if you prefer a softer contrast with your jeans.
What If You Prefer Flats Instead of Pumps?
Many readers wonder whether this French girl denim look still works with loafers or ballet flats. The answer is yes, with one caveat. The hem of the jeans should be adjusted. If you wear flats, the jeans should graze the top of your foot without pooling on the ground. A slight ankle break is acceptable, but excessive bunching will make the outfit feel sloppy rather than relaxed. Loafers in black leather or suede complement the blazer’s formality, while ballet flats keep the look softer and more daytime-appropriate.
2. The East-West Shoulder Bag: A Parisian Accessory Staple
Emma Roberts carried a Balenciaga Le City East-West shoulder bag in leather. This bag is a variation of the iconic City bag, but the east-west orientation — wider horizontally than vertically — gives it a distinct silhouette. Parisians have long favored east-west shapes because they sit neatly against the hip without protruding too far forward or backward. This creates a streamlined profile that does not disrupt the line of the blazer.
Why East-West Bags Feel Particularly Parisian
The east-west bag gained popularity in Paris during the early 2000s, when designers like Balenciaga and Celine introduced elongated shapes that fit snugly under the arm. Unlike oversized totes or slouchy hobos, the east-west bag forces you to carry less, which aligns with the Parisian philosophy of editing your belongings. It also encourages a certain posture — the bag stays close to the body, freeing your hands and allowing you to move with ease.
How to Choose an Alternative
If the Balenciaga Le City East-West is outside your budget, look for a similar shape from brands like Mango, COS, or Everlane. The key details are a structured silhouette, a top handle or a short shoulder strap, and minimal hardware. Avoid bags with large logos or busy patterns. The bag should feel like a quiet complement to the blazer and jeans, not a statement piece.
3. The Straight-Leg Jean Fit: Finding Your Perfect Silhouette
Not all straight-leg jeans are created equal. The pair Emma Roberts wore had a high rise and a relaxed fit through the thigh, tapering slightly at the ankle. This specific cut avoids the extremes of skinny jeans or wide-leg trousers. It sits in the middle, offering enough room for comfort while maintaining a polished line.
How to Choose the Right Fit
Start with the rise. A high-rise jean, sitting at or just above the natural waist, creates a longer leg line when paired with a blazer. The blazer should end at or just below the hip bone, leaving a small gap between the hem of the blazer and the top of the jeans. This gap prevents the outfit from looking like a uniform and adds a sense of proportion.
Next, consider the fabric. Look for denim with about 2 to 3 percent elastane for a little stretch, but avoid anything that feels like jeggings. The denim should hold its shape after several wears. A rigid or selvedge denim works well if you prefer a more authentic vintage feel, but it requires a break-in period.
What If You Have a Different Body Type?
For those with a curvier frame, a straight-leg jean with a slight taper at the ankle can balance the hips. Avoid jeans that are too tight through the seat, as they can create a muffin-top effect under the blazer. For those with a straighter build, a high-rise straight leg with a bit of volume through the thigh adds the illusion of curves. The goal is a fit that skims the body without gripping it.
4. The Black Pump: Elevating Denim Without Overcomplicating It
Emma Roberts wore black pumps with her outfit. This choice is not accidental. Black pumps are the Parisian equivalent of a neutral handshake — they say “I am dressed, but I did not try too hard.” The heel height matters. A pump with a 2.5 to 3 inch heel lengthens the leg without making walking difficult. A stiletto heel adds a touch of sharpness, while a block heel feels more grounded. Either works, as long as the shape is simple and the color is black.
Can You Wear This Look for Daytime Errands?
Absolutely. Swap the pumps for black leather loafers or low-heeled mules, and the outfit transitions seamlessly from evening to daytime. The key is to keep the blazer and jeans unchanged. The blazer provides enough structure to elevate the denim, so even with flat shoes, the look remains intentional. If you are running errands, consider rolling the cuffs of the jeans once or twice to show a bit of ankle, which keeps the silhouette fresh.

Step 1: Choose Your Blazer
Select a collarless blazer in black or a dark neutral. Ensure the shoulders fit well — the seam should align with your shoulder bone. The length should fall between your hip and mid-thigh. If the blazer is too long, it will overwhelm the jeans. If it is too short, it will break the vertical line.
Step 2: Pick Your Jeans
Find a high-rise straight-leg jean in a medium to dark wash. Avoid distressed or ripped denim for this look. The wash should be even and subtle. If you are between sizes, size up for a relaxed fit. You can always take in the waist if needed.
Step 3: Select Your Shoes
For evening, choose black pumps with a 2.5 to 3 inch heel. For daytime, choose black loafers or ballet flats. The shoe color should match the blazer as closely as possible to create a continuous dark line from top to bottom.
Step 4: Add One Bag
Choose a structured shoulder bag in an east-west shape if possible. Black or dark brown leather works best. Keep the bag small enough to fit under your arm without protruding. Avoid oversized totes or backpacks.
Step 5: Edit Everything Else
Remove any jewelry that does not serve a clear purpose. A simple watch or a thin chain necklace is fine. Skip the belt, the scarf, and the statement earrings. Let the outfit breathe.
Common Pitfalls to Avoid
Even with the right pieces, small mistakes can derail the look. Here are three frequent errors and how to fix them.
Pitfall 1: The Blazer Is Too Baggy
A blazer that is too loose will make the outfit look sloppy rather than relaxed. The shoulders should fit snugly, and the body of the blazer should not gap at the chest. If you are between sizes, choose the smaller one and consider having it tailored.
Pitfall 2: The Jeans Are Too Long
Jeans that puddle over the shoes create a messy hemline. For pumps, the hem should just graze the top of the shoe. For flats, the hem should hover about half an inch above the ground. Take your jeans to a tailor for a proper hem if needed.
Pitfall 3: The Bag Is Too Casual
A canvas tote or a sporty crossbody bag will clash with the blazer’s formality. Stick to leather or high-quality faux leather. The bag should have clean lines and minimal hardware. A zip-top closure is more polished than an open tote.
Why This Look Works for So Many Occasions
The straight-leg jean and black blazer combination is remarkably versatile. It can take you from a lunch meeting to a dinner party with only a shoe change. It works for travel because the pieces pack flat and resist wrinkles. It suits a range of body types because the proportions are forgiving. Most importantly, it requires no complicated layering or fussing. You put it on, and you are ready.
For someone who is traveling to Paris and wants to adopt the local effortless style without buying a whole new wardrobe, this one outfit can serve as the foundation for an entire trip. Pack the blazer, one pair of straight-leg jeans, a few simple tops, and one pair of black shoes. Mix and match. You will look like a local without trying to imitate anyone.
