The best white button-up shirts come down to proportion. A close-cut shirt under a blazer, an easy poplin shirt with jeans and a cropped shirt with high-waisted trousers solve different wardrobe problems. The trick is finding the one that looks intentional on you, rather than buying another oversized shirt and hoping the sleeves work.
This edit starts with Balzac Paris, the Parisian label behind the natural-white Léonor. From there, it moves through fitted, relaxed, petite and tall options, with two more sculptural cropped shirts at the end. All are white or natural white, but the collars, cuffs, lengths and fabrics make the difference.

White button-up shirts with a tailored shape
A softer Parisian collar: Balzac Paris Léonor
Balzac Paris’s natural-white shirt with a ruffled collar is the feminine alternative to a plain office shirt. The organic cotton and easy shape keep it from feeling formal; the collar is the detail to leave showing above a crewneck. It measures 67 cm from the shoulder in a size 36. Choose your usual size according to the brand’s guide, and remember that natural white is a softer shade than optic white. Shop here
A fitted white shirt for blazers: Theory
Theory’s fitted white stretch-cotton shirt is the sharpest option here if you want a shirt to follow the waist rather than float around it. The hidden placket, adjustable cuffs and rounded hem look clean under tailoring. The fabric has stretch, so this is a different proposition from a loose, all-cotton poplin shirt. Check the fit through the bust while seated before deciding the size is right. Shop here
A petite white shirt with a cleaner tuck: Boden Sienna
Boden’s white cotton shirt in petite and regular lengths is the practical starting point when sleeves and torso length are usually the problem. The Sienna comes in both proportions, so compare the two size guides instead of sizing down just to shorten the shirt. Wear it tucked into straight-leg jeans with the collar open. The right proportion will do more for the result than rolling the sleeves again. Shop here
An easy white poplin shirt: Alex Mill Jo
Alex Mill’s relaxed white cotton-poplin shirt gives you room without the deliberately exaggerated scale of a big boyfriend shirt. The chest pocket and curved hem make it a good everyday option with denim. Try a loose front tuck with high-rise jeans, or wear it open over a simple tank. If you want a close fit under a narrow blazer, choose the more fitted Theory shape instead. Shop here
Relaxed white button-up shirts that still look polished
Relaxed should mean ease through the shoulder and body, not a collar that swallows your neck. Look at where the shoulder seam lands and how much fabric gathers at the waist. A half tuck can show the waistband without forcing a long hem into fitted trousers.

A crisp boyfriend shirt: With Nothing Underneath
With Nothing Underneath’s white fine-poplin boyfriend shirt is for the deliberately borrowed-from-the-boys look. Fine poplin keeps the line crisp rather than slouchy. Balance its roomy shape with a straighter trouser or narrower jean, and let the cuff show under a sweater. Use the brand’s size chart, especially when comparing its UK sizing with a US shirt you already own. Shop here
A more substantial white oxford shirt: Everlane
Everlane’s relaxed white oxford shirt has the everyday character of a menswear oxford rather than the smooth finish of fine poplin. Choose it for a casual cuff, an open collar and jeans or chinos. It is a useful distinction if you find very crisp shirts too dressy. Size availability is limited, so check your size before making this the anchor of an outfit. Shop here
A longer white poplin shirt: Banana Republic
Banana Republic’s white cotton-poplin shirt with a curved hem has a longer, easy line that works tucked or left out. It comes in regular and petite, so compare the two size guides before you order. The chest pocket and button cuffs keep it from looking plain, and it sits well under a sweater or open over a tank. Try a half tuck with straight-leg trousers. Shop here

A big white shirt with more sizing options: Gap
Gap’s oversized organic cotton-poplin white shirt is the easy, longer-line choice. The New Optic White version has a chest pocket, button cuffs and regular, tall and petite fit options. The brand marks this Big Shirt as a best seller. Keep the bottom half simple to balance the volume: straight jeans or a slim trouser will make the oversized shape look considered. Shop here
A cropped white shirt with an adjustable hem: Loewe
Loewe’s cropped white cotton-poplin shirt with a gathered hem changes the silhouette rather than adding another standard long shirt. The concealed placket keeps the front clean, while the adjustable hem brings volume to the waist. It makes the most sense with a high-waisted skirt or trouser. Check where the cropped hem sits on your torso; it is not the pick for a deep, secure tuck. Shop here
A high-collar cropped white shirt: Alaïa
Alaïa’s cropped white poplin shirt with a ruffled high neckline is the statement option. The high collar and short body make it closer to a tailored going-out piece than a basic office shirt. Wear it with high-waisted trousers and leave the neckline as the focal point. The listed fit guidance recommends sizing up; use the measurements rather than assuming your usual shirt size will work.

How to choose the best white button-up shirt for you
Start with the shoulder. A tailored shirt should sit neatly without pulling across the back. A dropped shoulder is fine when it is an intentional relaxed shape, but compare the sleeve length too.
Test the front while seated. Button the shirt, sit down and move your arms. A shirt that looks smooth standing can pull at the bust or waist at a desk. Sizing up may add too much length, which is why petite, tall and fitted cuts matter.
Match the fabric to the job. Smooth poplin gives a crisp line, oxford feels more casual, and stretch cotton can suit a closer fit. White fabric can vary in opacity, so check it in daylight with the underlayer you plan to wear. None of these picks is a blanket promise of opacity.
Choose one clear proportion. Keep an oversized shirt loose with a straighter bottom, or tuck a fitted shirt into a fuller trouser. A cropped shirt works best when you have already settled on the waist height. A white shirt should make the rest of the outfit easier.
Keep it crisp. A handheld garment steamer removes creases in minutes, a stain remover pen handles a lunch spill before it sets, and collar stays keep a pointed collar flat under a blazer.
