Designer Jackets & Blazers
Refined tailoring meets effortless wearability in our collection of designer jackets and blazers, created for women who value structure, softness, and timeless design in equal measure. At IDA+S, each piece is thoughtfully crafted to move with you through real life, from polished mornings at work to relaxed evenings and weekend escapes.
Our range spans tailored wool blazers in single and double breasted silhouettes, oversized and relaxed jackets, linen suit blazers, leather and bomber styles, quilted layers, lightweight travel jackets, and tweed or textured designs. Whether you gravitate toward sharp tailoring or softer, contemporary shapes, IDA+S offers a considered balance of modern form and enduring elegance.
Tailored Craftsmanship, Designed to Last
Premium materials sit at the heart of every jacket. We work with merino and Italian wool (including wool blends) for warmth and structure, cashmere for softness, pure silk and silk linen blends for lightweight luxury, alongside premium linen, leather, tweed, and textured fabrics. These elevated textiles are chosen not only for how they feel, but for how they wear over time, ensuring your jacket becomes a lasting part of your wardrobe.
From tailored blazers designed to anchor your workwear to relaxed outer layers that bring ease to everyday dressing, IDA+S jackets are created to adapt to your lifestyle. Style a sharp wool blazer with tailored pants for sophisticated office dressing, or layer an oversized jacket over denim and knits for a softer, off duty look. Each silhouette is designed to complement the broader IDA+S wardrobe, pairing seamlessly with our
women’s designer clothes, transitional
coats, and cozy
sweaters and knits.
Color plays a quiet yet powerful role in our collections. Our jackets and blazers are offered in a curated palette of versatile neutrals and seasonal tones, from classic black, navy, and soft greys to warm earth shades and understated pastels. These thoughtfully selected hues allow for effortless styling across seasons, helping you build outfits that feel cohesive, elevated, and uniquely yours.
Behind every IDA+S garment is a commitment to responsible craftsmanship. Guided by the legacy of Ida Siu and brought to life through our vertically integrated, LEED certified supply chain, each jacket reflects our belief in sustainable luxury. By working directly with our facilities, we ensure ethical production, material transparency, and garments made with care from start to finish.
Finding the Right Fit and Caring for Your Jacket and Blazer
Finding the right fit is essential to how a jacket feels and performs. Each IDA+S style includes a detailed sizing guide on its product page, with measurements for bust, shoulders, and length. From the clean lines of a tailored blazer to the relaxed drape of an oversized jacket, our guides help you select the silhouette that suits your shape and styling preferences.
To preserve the beauty of your IDA+S jacket, we recommend professional dry cleaning for wool, cashmere, silk, and tailored styles. Linen pieces may be gently steamed to refresh their shape. Always follow the care label on each garment, store jackets on structured hangers, and avoid prolonged exposure to direct sunlight to maintain color and fabric integrity.
With IDA+S, you’re choosing thoughtfully designed outerwear that blends modern tailoring with enduring craftsmanship, pieces created to support you through every season of life.
