Button Up Lapel Collar Blazer | Deep Teal / S 100100675961556

How to measure

To choose the best size, measure carefully and compare your results with the product size chart. Use a soft measuring tape, measure over light clothing, stand naturally, and keep the tape level and relaxed.

Measure your body

• Bust/Chest: Wrap the tape around the fullest part of your chest, under the arms and across the shoulder blades. Keep the tape level and relaxed.
• Waist: Measure at your natural waistline (the narrowest part) while standing straight and breathing normally.
• Hips: Measure around the fullest part of your hips and seat with feet together.
• Shoulder width: Measure from the outer edge of one shoulder to the other across the back where shoulder seams normally sit.
• Sleeve length: Slightly bend your elbow and measure from the shoulder seam (or where you want the shoulder seam to sit) to the wrist.
• Back length: From the base of the collar (where collar meets body) straight down to the hem.

Measure a blazer (garment)

• Chest (pit-to-pit): Button the blazer and lay flat. Measure across from armpit seam to armpit seam and double for circumference.
• Shoulder width: Measure from one shoulder seam to the other across the back.
• Sleeve length: From shoulder seam to cuff, measured on the outer edge of the sleeve.
• Center back length: From the base of the collar to the bottom hem along the center back.
• Hem width: Measure straight across the bottom edge and double for circumference.

Fit guidance: For a tailored look allow ~1–2 inches (2–4 cm) of ease at the bust; for a relaxed or layered fit allow ~2–3 inches (5–8 cm). If between sizes, consider sizing up for easier layering.

Materials

Blazers of this style are commonly constructed from a few typical fabric families. Always check the product label for exact fiber content.

• Wool or wool blends: Structured, warm, breathable, and good for fall/winter. Often dry-clean only and holds shape well.
• Polyester/viscose blends: Smooth drape, wrinkle-resistant, easy care; may include a small percent of elastane for stretch and comfort.
• Linen blends: Lightweight and breathable for warmer months; tends to wrinkle more and may require gentler care.
• Cotton blends: Comfortable and breathable; care can vary by construction—check label for washability.
• Linings & trims: Linings are commonly polyester, acetate or viscose for a smooth feel; buttons may be resin, horn-look or metal; internal interfacing and shoulder pads add structure.

If you have sensitivities or need precise care instructions, view the exact fiber composition on the product page or garment label before purchase.

Care guide (to keep it lovely longer)

• Check the label first: Follow the garment care instructions—some blazers are dry-clean only, others are washable.
• Spot clean: Treat small stains immediately with a damp cloth and mild detergent; test on an inconspicuous area first.
• Dry cleaning: For wool or fully structured blazers, professional dry cleaning maintains shape and lining integrity.
• Machine or hand wash: If the label allows, wash gentle/cold and use a mesh bag to protect the blazer and hardware.
• Drying: Reshape and hang on a wide, supportive hanger to air dry—avoid tumble drying.
• De-wrinkle safely: Use a steamer to remove wrinkles; if ironing, press inside out with a cloth between iron and fabric on a low-to-medium setting.
• Storage: Store on a broad hanger to preserve shoulder shape. Use breathable garment bags and natural moth deterrents (cedar, lavender) for long-term storage.
• Maintenance: Replace loose buttons and mend seams promptly. Brush fabric gently to remove lint and extend the interval between cleanings.

Style tips

• Workwear: Button up and pair with matching trousers or a pencil skirt and a silk or crisp cotton blouse for a sharp professional look.
• Smart casual: Layer over a tee or lightweight knit with slim jeans and loafers or sneakers for an elevated everyday outfit.
• Layer a dress: Wear over a slip or midi dress to mix structured tailoring with soft silhouettes.
• Add a belt: Cinch with a leather or statement belt for instant waist definition and a modern silhouette.
• Play with proportion: Team an oversized blazer with tapered trousers or a cropped blazer with high-waisted wide-leg pants.
• Shoe pairings: Heels and pointed-toe shoes for formal looks; ankle boots and loafers for transitional styling; white sneakers for casual contrast.
• Accessories: A silk scarf, brooch, or layered necklaces elevate the blazer. Keep accessories aligned with the outfit’s formality.

Quick fit check: When buttoned, the blazer should lie smoothly across the bust without pulling; shoulders should sit at your own shoulder line; sleeves should reach the wrist bone (or be styled slightly pushed up for a casual vibe).
