Men's Full Size Button Up Long Sleeve Shirt Plus Size | Dark Gray / S 100400297941968

How to measure — get the right fit

Measure the shirt (garment laid flat)

1. Lay the shirt flat: Button up, smooth out wrinkles and lay on a flat surface.
2. Chest (pit-to-pit): Measure straight across from one armpit seam to the other. Double that number to get the full chest circumference (e.g., 24" flat = 48" chest).
3. Shoulder width: Measure from shoulder seam to shoulder seam across the back.
4. Sleeve length: Measure from the shoulder seam to the end of the cuff. (If you prefer, measure from the center back of the neck to the cuff for overall sleeve length.)
5. Body length: Measure from the highest point of the shoulder (where the collar meets the shoulder) straight down to the bottom hem.
6. Hem width: Measure straight across the bottom hem and double the number for circumference.
7. Cuff width: Measure across the closed cuff and double to get the circumference.
8. Collar / neck band: Measure the inside base of the collar from end to end and double for collar circumference.

Record measurements in inches and centimetres (1 in = 2.54 cm) and compare to the product size chart. If you are between sizes or plan to layer, choose the larger size for extra comfort.

Measure your body (for best fit)

• Chest: Measure around the fullest part of your chest, under the arms, keeping the tape level.
• Shoulder: Find the bony point at the edge of each shoulder and measure across the back between them.
• Sleeve: With a slightly bent elbow, measure from the shoulder point to the wrist bone.
• Neck: Measure around the base of your neck where a collar would sit.
• Waist & Hips: Measure around your natural waist and the fullest part of your hips; helpful when tucking the shirt in.

Fit guidance: allow ~2" of ease for a fitted look, ~3–4" for a standard/comfortable fit, and 5"+ for an oversized/relaxed fit. Shoulders are the most important — the shoulder seam should land at your shoulder bone.

Materials & construction — what to look for

Check the product label or listing for exact composition. Common fabric types for men's full-size / plus-size long-sleeve button-ups and what they mean:

• 100% Cotton (poplin, broadcloth): Breathable, soft, crisp finish; may shrink slightly if not pre-shrunk.
• Cotton–Polyester blends (e.g., 60/40, 65/35): Better wrinkle resistance, easier care, less shrinkage.
• Oxford cloth / chambray: Textured, durable, casual look that softens with wear.
• Flannel (brushed cotton): Warm, soft, ideal for cooler weather.
• Linen or linen blends: Very breathable and airy — great for warm weather, wrinkles more easily.
• Stretch blends (1–3% elastane): Adds mobility and comfort across the chest and shoulders.

Construction details to note: button material (resin, plastic, or mother-of-pearl), reinforced seams and bartacks at stress points, double-needle topstitching, placket and collar type, and whether there is a chest pocket. Fabric weight (light/medium/heavy) affects drape and seasonality — check product notes for ounces or GSM when available.

Model information (reference)

The photos are provided for fit reference. Example reference measurements (use as a guide):

• Reference model: Height: 6'0" (183 cm) — Chest: 44" (112 cm) — Wearing size: 2XL (plus-size fit shown)
• Fit shown: Relaxed / true-to-size for a full-size cut with room through the chest and torso; sleeves hit at the wrist bone.

If you prefer a closer fit, choose one size smaller; for layering or a more relaxed look, size up. Always compare the garment’s flat measurements to a shirt you already own for best results.

Care guide (to keep it lovely longer)

• Machine wash cold with like colors on a gentle cycle. Turn the shirt inside out to protect buttons and finish.
• Use a mild detergent; avoid chlorine bleach. Use non-chlorine bleach only when needed.
• Tumble dry low or, preferably, hang to dry to reduce wear and shrinkage. Remove promptly from dryer to minimize wrinkles.
• Iron inside out on medium heat (higher heat for 100% cotton if needed). Use steam or a garment steamer for quicker wrinkle removal.
• For linen or delicate finishes, wash on a gentle cycle and hang dry. For flannel, wash cold and tumble low to keep softness.
• Treat stains promptly: blot (don’t rub), pre-treat with a stain remover or mild detergent, then launder.
• Store on a wide hanger to preserve shoulder shape; button the top button or two to maintain collar alignment.
• Avoid over-washing — airing garments between wears and spot-cleaning can prolong life.

Style tips

Casual

• Wear untucked over jeans or chinos; roll the sleeves once or twice for a relaxed feel.
• Pair with sneakers or casual boots and a plain tee underneath for a modern layered look.

Smart casual & office

• Tuck into tailored chinos or trousers, add a leather belt and loafers for a polished appearance.
• Layer under a blazer or sport coat — pick a slimmer outer layer if you want a neater silhouette.
• For ties, choose a medium-width knot and a shirt with a crisp collar.

Seasonal & layering

• Under a sweater: let the shirt tail peek out for contrast; collar worn over the sweater neck looks neat with casual layers.
• Over a tee: leave the shirt unbuttoned for a laid-back look in spring or early fall.
• Flannel and heavier Oxfords are great fall/winter; lightweight poplin and linen blends are ideal for warm months.

Plus-size fit & proportion tips

• Focus on shoulder fit — the seam should sit at the edge of your shoulder bone.
• Opt for vertical details (subtle pinstripes) or darker solids to create a lengthening effect.
• Avoid overly baggy cuts; structured fabrics with a little weight drape better and avoid adding unnecessary bulk.
• Keep shirt length proportional — hem should land near the mid-zipper area of your trousers when tucked or just below the belt when untucked for balanced proportions.
• Use a well-placed belt to define the waist when tucking; adding a lightweight jacket can create clean vertical lines.

Quick tip: compare a favorite shirt laid flat to the garment measurements above before ordering — this is the most reliable way to get the fit you want.
