Leggings with an oversized shirt: the formula for the perfect look

One of my clients, a top manager at a large IT company, once complained during a morning consultation: "Julia, I'm trying to put together a relaxed weekend look, but I always look like I forgot to change out of my pajamas or like I'm just coming back from a workout." We opened her closet, and the problem was immediately apparent. She was trying to pair thin cotton leggings with a soft, shapeless shirt. No structure, no rigid lines. Once we swapped the soft cotton for crisp, shapely poplin and the fine knit for dense Ponte di Roma, the magic happened.

Today leggings with an oversized shirt — this isn't just clothing for going out for coffee. It's a precise architectural formula that requires an understanding of proportions and textures. We discussed the anatomy of the perfect leggings in more detail in our The complete guide to styling leggings in the city , and today I want to explore the top half of this equation. Why is buying something three sizes too big a fatal mistake? And how can you make basic pieces look like a million bucks?

Leggings with an oversized shirt: Why this formula has become a modern classic

For a long time, the combination of a fitted bottom and a loose top was considered exclusively a casual or sporty affair. This transformation occurred thanks to Scandinavian street style influencers, who were the first to understand the cardinal principle of styling: comfort shouldn't exclude elegance.

The secret lies in the rule of contrasting volumes. Fitted bottoms (leggings) act as a blank canvas, highlighting the slenderness of your legs, but they also require compensation. If you wear a tight top, the look will be too provocative or overtly sporty. But add an architectural, rigid top, and you achieve the perfect balance. This is clothing psychology at its finest: you feel relaxed thanks to the elastic bottoms, but look put-together thanks to the collar and cuffs of the shirt.

Image Architecture: How to Choose the "Correct" Oversized Look

In my 12 years as a stylist, I've constantly encountered the same misconception. Women go to the men's department at Zara or COS, pick up an XXL shirt, and wonder why it fits so sloppily. Remember: true oversize looks are different.

A proper voluminous shirt has a dropped shoulder line and widened armholes, but the collar and cuffs remain your size If your collar is three centimeters off your neck, you don't look stylish, but rather like you're wearing someone else's clothes.

"At the Marangoni Institute, we were taught the golden ratio in clothing design. The ideal length of an oversized shirt paired with leggings should cover exactly two-thirds of the buttocks. If it's shorter, you're cutting off the proportions and visually shortening the legs. If it's longer, you're turning the shirt into a skimpy dress."

Another critical aspect is the rigidity of the details. The taped collar and cuffs give the shirt a classy look. They create the frame for the face and wrists that holds the entire look together.

Fabric makes all the difference: poplin, silk or linen

Not every fabric can stand up to the jersey of leggings. The rule of texture contrast applies here:

• Crispy poplin: An absolute favorite. Look for 100% cotton with a minimum weight of 120 g/m². It should literally "stand up" and form beautiful, firm folds, rather than flowing softly over the body.
• Thick silk: Ideal for evening outings and a smart-casual aesthetic, it should be a heavy crepe de chine or thick satin that's not see-through and has some heft.
• Flax: A wonderful summer option, but with a caveat. To avoid the "wrinkled pajamas" effect, choose blends (linen with cotton or viscose)—they wrinkle less and hold their shape better.

A Basic Shirt: Why Sports Leggings Ruin Everything

I remember a shoot in Milan a couple of years ago. The model was wearing a stunning silk shirt from a premium brand, costing around 800 euros. But the look stubbornly looked cheap. The reason? The assistant gave her regular sports leggings made of thin supplex. The distinctive shine of the synthetic athletic fabric and the flat seams instantly killed the elegance of the silk.

Thin biflex clashes with the expensive fabric of the shirt. For the city, you need leggings made of Ponte di Roma This dense double-knit fabric works like a lightweight corset: it's matte, completely opaque (passes a rigorous "squat test"), and doesn't stretch out at the knees. High-quality matte faux leather is also an excellent alternative.

The Art of Casual: 3 Ways to Style Leggings with an Oversized Shirt

Buying the right pieces is only half the battle. How you wear them determines the final result. On fashion shoots, we spend 15 minutes creating that perfect "casual" casualness. Here are three tricks you can use right now:

1. French dressing (French tuck): Tuck just the front of your shirt (right in the center, about the width of a palm) into your leggings, leaving the back and sides exposed. This is a genius trick: it defines your waist and elongates your legs while still covering the back of your thighs.
2. J.Crew roll technique: Never roll your sleeves up. Unbutton the cuff. Fold the cuff up until it's just above your elbow. Then, fold the remaining sleeve up until it overlaps the bottom of the cuff. Leave the cuff edge exposed. This reveals the thinnest parts of your arms (like your wrists) and makes a bulky top look lighter.
3. Flying gait effect: Wear a basic ribbed crop top or tank top underneath the shirt. Button the shirt only two buttons down the middle (at chest level), leaving the bottom half unbuttoned. As you walk, the shirt tails will flutter, creating a beautiful movement and vertical lines that flatter the look.

From sneakers to loafers: footwear and accessories

Shoes and bags are the switches that change the mood of your outfit. Leggings with an oversized shirt are a blank canvas. According to McKinsey's global report on the state of fashion (2024), it is the accessory group that defines the DNA of a look today, allowing the same basics to migrate from the office to the restaurant.

If you want to go for preppy aesthetics, choose chunky loafers (in the style of Prada or Gucci) and complement them with white ribbed cotton socks. This instantly elevates the look. For a more dynamic, urban vibe, retro sneakers are ideal—for example, the classic New Balance 530 or the ubiquitous Adidas Samba.

But if you have a dinner or informal meeting in the evening, simply swap out the flats for kitten heel mules or slingbacks. And the main rule: since both the leggings and the shirt have soft lines, you need rigid frame bag Research from analytics platform Lyst shows that adding a bag with a clear geometric shape (such as a thick leather tote) visually increases the formality of an outfit by 40%.

Layering: Leggings and an oversized shirt for colder weather

With the arrival of fall, this formula remains relevant; it simply requires incorporating the "third layer" rule. Layering not only keeps you warm, but also makes your outfit look more expensive.

The simplest and most aristocratic trick in the old money style is a chunky knit sweater or cashmere jumper draped over the shoulders Over a shirt. Tie the sleeves into a loose knot at the chest. This creates an additional horizontal line in the portrait area and draws attention away from the hips.

To create a harmonious image at the intersection of business and relaxed styles , wear a voluminous, structured, "man-style" jacket over the shirt. Important: the jacket should be at least a couple of centimeters longer than the shirt, otherwise it will create an untidy effect with pieces of fabric sticking out from underneath. In cool weather, a classic double-breasted maxi trench coat is a great finishing touch.

Key Mistakes: When an Image Looks Cheap

Even the most carefully crafted formula can be ruined by poor execution. Here are the main mistakes I regularly correct during wardrobe reviews:

• A shirt made of thin viscose or cheap polyester. This fabric doesn't hold volume; it just hangs like a dull rag, highlighting all the nuances of your figure that you might have wanted to hide.
• Incorrect length. If your shirt hem ends right at the widest part of your hips, you're creating a horizontal line there that visually adds 5 kilograms to your weight. Fair Limit: This advice doesn't work for all body types. If you have a pronounced pear shape, your shirt should end either just above or just below your widest hip.
• Too much sports. Sports leggings with reflective stripes + foam-soled running shoes + a nylon backpack = you're not a stylish city girl, you're just heading straight from the gym. Mix up the sports elements with classic ones.

Checklist: Creating the Perfect Everyday Look

So, let's recap. To create a flawless look that will look expensive and appropriate for any occasion, go through this checklist before leaving the house:

1. Check the tightness of your leggings: Are they completely matte? Are the seams hidden? Are the knees not see-through when bent? If so, you've passed the first stage.
2. Rate this shirt: Is the collar stiff? Is the fabric crisp? Does the length cover two-thirds of the buttocks? Excellent, the architecture is well-designed.
3. Open the "choke points": Roll up your sleeves (J.Crew roll) to show off your wrists. If your shoes allow, leave your ankles exposed. Unbutton the top buttons to reveal your collarbones.
4. Add structure: Grab a tough leather bag or layer a structured jacket over it.

Fashion today isn't about complex, breathable designs. It's about choosing the right textures and mastering proportions. Invest in thick cotton and high-quality knitwear, and this simple combination will serve you faithfully for seasons to come.
