Product Insights
The Fine Pyjama-Stripe Shirt from Le 31 combines the crispness and breathability of lightweight poplin with a standard fit that drapes away from the body, keeping the wearer cool and comfortable; however, the cotton poplin wrinkles with wear, which suits the relaxed, nonchalant aesthetic, and the shirt is semi-sheer in lighter colors, requiring a light undershirt to avoid visible skin.
- Breathability
Lightweight poplin runs cooler than oxford or twill dress shirts.
Why this is supported
The poplin fabric is lightweight,
typically weighing 100–140 GSM
What is the fabric weight (e.g., oxford cloth weight, poplin weight) and is the shirt semi-sheer or opaque?. Its fine yarns and tight weave
allow constant air exchange — releasing body heat and vapor
How cotton poplin feels and breathes — lightweight_breathability. The fabric also
can absorb up to 25% of its weight in moisture before feeling damp
How cotton poplin feels and breathes — moisture_absorption_capacity, contributing to evaporative cooling.
- Fabric hand
Crisp, clean surface resists clinging and drapes away from skin.
Why this is supported
The fabric's hand is crisp and clean, as it
stays clean and crisp rather than fuzzy
How cotton poplin feels and breathes — softness_source. This results in
a smooth, slightly crisp surface that keeps the fabric from clinging to the body in hot weather
How cotton poplin feels and breathes — crisp_structured_hand. Additionally,
Poplin’s inherent body creates a drape that stands slightly away from the skin
How cotton poplin feels and breathes — drape_and_airiness, contributing to an airy feel.
- Collar structure
Crisp poplin keeps collar and placket sharp all day without a tie.
Why this is supported
The poplin's crispness gives it enough body that the collar and placket stay sharp:
maintaining sufficient body to keep the collar and placket looking sharp throughout the day
How cotton poplin feels and breathes — crisp_structured_hand.
- Sheerness
Semi-sheer in lighter colors; a light undershirt prevents visible skin.
Why this is supported
Catalog observed in the product Q&A that the poplin can be semi-sheer, especially in lighter colors such as Blue.
Poplin's tight plain weave means it can be semi-sheer, especially in lighter colors like blue
What is the fabric weight (e.g., oxford cloth weight, poplin weight) and is the shirt semi-sheer or opaque?As a result, a white or light gray undershirt is recommended to avoid visible skin; dark undershirts may contrast through the fabric.
- Layering comfort
Loose fit and breathable poplin keep the shirt comfortable when layered without bulk.
Why this is supported
The standard fit's straight, loose cut provides ample room for an undershirt without adding bulk. The 100-140 GSM poplin weave
the fine yarns and tight weave allow constant air exchange — releasing body heat and vapor — so the shirt runs noticeably cooler than heavier oxford or twill dress shirts
How cotton poplin feels and breathes — lightweight_breathability, so even with an undershirt the shirt remains cool. Additionally, the crisp poplin surface
keeps the fabric from clinging to the body in hot weather
How cotton poplin feels and breathes — crisp_structured_hand, preventing the shirt from sticking to the undershirt and maintaining a clean silhouette.
- Wrinkle behavior
Wrinkles develop over a day, enhancing the shirt's relaxed, nonchalant look.
Why this is supported
Catalog verified that the shirt's lightweight cotton poplin fabric is breathable and stays cool. The fabric
wrinkles readily with wear — elbow creases and seat lines will develop over the course of a day
How cotton poplin feels and breathes — wrinkle_character, which the design embraces as part of its nonchalant, loungy character. The straight, loose cut allows wrinkles to form naturally, and the pyjama stripe pattern reinforces the carefree aesthetic.
- Wrinkle removal
Can be ironed on medium heat to switch between rumpled and crisp looks.
Why this is supported
While the shirt is designed to look good wrinkled, it can also be pressed for a crisp appearance. Catalog verified the care instructions:
We recommend machine washing this shirt in cold water, tumble drying on low, and ironing on medium heat.
What are the specific care instructions (machine wash temperature, tumble dry recommended, ironing tips) and does the shirt shrink after washing?This means ironing is straightforward, allowing the wearer to choose between a casually rumpled and cleanly pressed look.
- Drape
Lightweight poplin drape keeps the standard fit airy and cool without billowing.
Why this is supported
Catalog verified that the poplin's inherent body creates a drape that avoids cling and billowing,
Poplin’s inherent body creates a drape that stands slightly away from the skin, which works with the loose standard fit to provide an airy, non-binding feel that avoids both cling and excess billowing.
How cotton poplin feels and breathes — drape_and_airiness, and at a lightweight 100-140 GSM, the fabric's air exchange keeps the shirt noticeably cooler than heavier oxford or twill dress shirts, as detailed by research.

- Care
Machine wash cold, tumble dry low, iron on medium heat.
Why this is supported

We recommend machine washing this shirt in cold water, tumble drying on low, and ironing on medium heat.
What are the specific care instructions (machine wash temperature, tumble dry recommended, ironing tips) and does the shirt shrink after washing?These recommendations are designed to prevent shrinkage, as the cotton poplin can shrink with hot water or high heat drying. The lightweight fabric also absorbs moisture readily, making low-heat drying important. Additionally, the fabric wrinkles during wear, so ironing is needed to restore a crisp appearance.
Shrinkage is possible with hot water or high heat drying, so cool settings are advised.
