One-Button Sleeveless Longline Blazer | Black / S 100100916248063

Overview

This longline, sleeveless tailoring piece is built for a clean, modern silhouette: a single front fastening creates a defined waistline while the extended hem visually lengthens the torso. Its streamlined construction and minimal detailing make it a versatile outer layer that shifts easily between professional, smart-casual and evening looks. Because it is unlined and made from a woven synthetic, it hangs crisp and lightweight for easy layering without extra bulk.

Material details

The fabric is a woven polyester, a durable synthetic fiber commonly used in ready-to-wear tailoring. Polyester fibers are produced from polyethylene terephthalate (PET), which delivers stable color, good tensile strength and resistance to shrinking. Depending on the weave and finishing, polyester can present a matte or slightly lustrous surface and offers a sharp drape that holds structured shapes well — ideal for a tailored, longline piece.

Practical notes about this textile:

• Durability: resists abrasion and repeated laundering better than many natural fibers.
• Colorfastness: dyes tend to bond well, so color stays vivid through multiple washes.
• Care: low-maintenance compared with delicate natural fabrics; tolerates home laundering under the right conditions.
• Comfort trade-offs: lower inherent breathability than cotton or linen; may feel warmer in high heat if worn without airflow layers.
• Environmental considerations: polyester is recyclable and widely recycled into new fibers, but it is a petroleum-derived fiber and can shed microfibers into wastewater when washed.

Fabric advantages — pros & cons

Pros

• Easy-care — resists shrinking and most wrinkling, so it keeps a neat appearance with minimal fuss.
• Shape-retention — holds a crisp tailored silhouette over time.
• Lightweight structure — unlined construction keeps the garment breathable enough for layering without bulk.
• Color stability — less prone to fading than many natural dyes when washed appropriately.
• Travel-friendly — compresses and bounces back; good for packing.

Cons

• Less breathable than natural fibers — can feel warm in very hot, humid conditions when worn alone.
• Minimal natural stretch — fit must be chosen carefully to allow for movement and layering.
• Static and pilling — may produce static cling or show surface pills over long-term wear depending on friction and finish.
• Heat sensitivity — ironing/pressing requires caution to avoid shine or melting at high temperatures.
• Environmental impact — conventional polyester is petroleum-derived; prefer recycled options if sustainability is a priority.

How to measure this garment (step-by-step)

Measure the blazer laid flat on a smooth surface. Do not stretch the fabric while measuring.

1. Back length: from the center back at the base of the neck (or seam) straight down to the hem.
2. Bust (pit-to-pit): measure across from one underarm seam to the other, then multiply by two for the full circumference.
3. Shoulder width: seam-to-seam across the top of the back. If there are no shoulder seams, measure across the broadest point of the top shoulder.
4. Armhole circumference: measure around the arm opening; for sleeveless designs, this determines how much room you have over shirts or light layers.
5. Hem width: measure straight across the bottom edge and double for the full circumference.
6. Front opening / button placement: measure from the button to the hem if you want to confirm where the closure lies relative to your outfit.

Tip: measure a blazer you already own that fits how you like; compare those flat measurements directly to this garment's measurements for the most reliable fit check.

How to measure yourself to choose the right size

1. Bust / Chest: wrap the tape around the fullest part of your chest, keeping it level and snug but not tight.
2. Shoulder width: measure from the tip of one shoulder across the back to the tip of the other shoulder.
3. High hip: measure around the body where the hem of this longline piece will sit (stand straight and measure the widest point at the top of the hips).
4. Height: note your height to understand where the hem will fall on your body (the same garment length can hit differently depending on stature).
5. When measuring, wear the undergarments or light layers you plan to use with the blazer (e.g., blouse vs. thin knit).

Allowance guidance: because the fabric has very little stretch, allow at least 1–2 inches (2.5–5 cm) of positive ease at the bust for a fitted look or 3–4+ inches if you expect to layer bulky knitwear underneath. Shoulder fit is critical for comfortable movement — prioritize a shoulder measurement that feels correct over raw chest numbers if you must choose.

Fit notes

• The silhouette is clean and slightly elongated — it’s designed to skim the body rather than cling tightly.
• Because the interior is unlined, the shape relies on the outer weave and cut rather than internal structure; this yields a lighter feel but less built-in insulation.
• If you plan to wear thick sweaters or multiple layers beneath, consider sizing up to preserve mobility through the arms and chest.
• Shoulders should fit first: a tight shoulder will restrict movement even if the body feels roomy.

Model information — how to use product images as reference

Product photos are a visual reference for proportion. Typical e-commerce imagery uses models between about 5'7" and 5'11" wearing a small or medium as a demonstration — use any model height and size details shown on the product page to gauge where the hem falls on that height. If model specifics aren’t listed, compare the pictured fit to your own proportions and to the garment measurements above.

Color & pairing suggestions

Since this is a solid, minimalist layer, treat color as the starting point for outfits:

Neutral shades (black, navy, gray, beige)

• Office: pair with tailored trousers or a pencil skirt in a coordinating neutral, a silk blouse and pumps for a polished look.
• Casual: layer over a white tee and straight-leg jeans, finish with loafers or low-heeled boots.
• Texture play: combine matte suiting with soft knits, leather accessories or satin to add depth without complicating the palette.

Bright or jewel tones

• Contrast with muted bases like charcoal denim or cream trousers for a modern pop.
• Keep accessories minimal — a single metallic accent (belt buckle, chain necklace) lets the color sing.

Belt tip: cinch at the waist with a slim belt for a defined hourglass shape, or leave open for a relaxed column silhouette.

Style & occasions

• Work-ready: a minimalist tailored layer that reads professional over shirts and blouses, great for meetings and presentations.
• Smart-casual: throw it on over a tee and jeans to elevate a casual outfit instantly.
• Evening: wear over a slip dress or jumpsuit with heels and statement earrings for a streamlined, sophisticated look.
• Travel: lightweight construction and wrinkle-resistant behavior make it a convenient choice for business trips.

Seasonal guide

• Spring / Summer: ideal as a lightweight outer layer over sleeveless or short-sleeve tops when you want coverage without heat.
• Transition (early fall / late spring): pairs well with long-sleeve knits and thin turtlenecks; add a scarf when temps dip.
• Winter: can be used indoors as part of layered outfits; for outdoor use in cold climates, layer a coat over it or pick warmer, lined outerwear instead.

Care tips

• Wash on a cool or cold gentle cycle or use a delicates bag to reduce friction in the machine.
• Line dry or tumble low — remove promptly from the dryer to minimize wrinkling and shape distortion.
• Steam to refresh and remove wrinkles; if ironing is needed, use a low-heat setting and a pressing cloth to avoid shine.
• Avoid bleach and strong fabric softeners; these can degrade fibers or reduce breathability.
• Spot clean small stains promptly to avoid repeated washing — a mild detergent dabbed with a soft cloth often does the trick.

Care guide — keep it looking lovely longer

1. Rotate wear: give the piece time between wears to recover its shape and reduce pilling.
2. Use a quality hanger: a broad-shouldered hanger helps preserve shoulder lines; avoid thin wire hangers that can deform the silhouette.
3. Protect during travel: fold carefully or place in a breathable garment bag to prevent abrasion; if packing, roll with tissue paper to limit creases.
4. Remove pilling: treat any pills with a fabric comb or pill remover rather than aggressive rubbing.
5. Store away from sunlight: prolonged UV exposure can fade pigments over time.
6. Spot test treatments: if using a new detergent or stain remover, test it on an inside seam to confirm colorfastness.

Style tips — quick outfit ideas

• Office: buttoned over a crisp blouse, tailored trousers and loafers — minimal jewelry keeps the look modern.
• Weekend: worn open over a striped tee and high-rise jeans with white sneakers for an effortlessly chic vibe.
• Evening: layer over a slip dress with strappy heels and a clutch for a refined monochrome outfit.
• Layering: wear a thin turtleneck or fitted long-sleeve top underneath for cooler days; avoid bulky knits unless you sized up for layering room.
• Belt it: add a waist belt to transform the longline shape into a cinched, more feminine silhouette.
