Frequently Asked Questions

What is SIR. known for?

SIR. is an Australian contemporary womenswear label recognized for understated, feminine design. The collection at Saint Bernard spans silk separates, slip dresses, tailored trousers, and swimwear, often featuring exclusive prints and a relaxed yet refined sensibility suited to warm-weather and resort dressing.

How does SIR. sizing work?

SIR. uses a numeric size scale, commonly 0 through 4, rather than small to large labels. Most styles fit true to size, so take your usual size; silk separates wear relaxed, while slip dresses and swim sit closer to the body. Check the size guide on each product page for the best fit.

What fabrics does SIR. use?

SIR. favors natural and premium fabrics, including silk crepe de chine, viscose and silk blends, and cotton, alongside nylon and elastane in its swimwear. These materials give the collection its signature fluid drape, soft finish, and lightweight comfort for warmer climates.

How do I care for SIR. pieces?

Care depends on the fabric. Silk and viscose-silk styles are best dry cleaned or gently hand washed, while cotton pieces can usually be machine washed cold and laid flat to dry. Always follow the care label on each garment to protect prints and drape.

How can I style SIR. pieces?

SIR. is built for easy mixing. Layer silk shirts and trousers as coordinated sets, wear slip dresses for evening, or use lightweight separates and printed pieces as cover ups over swimwear. Neutral sandals and simple jewelry let the prints take center stage.

What occasions is SIR. best for?

SIR. suits warm-weather and resort occasions, from beach days and poolside lounging to garden lunches, holidays, and evening events. The blend of swimwear, breezy separates, and elegant slip dresses makes it easy to dress for travel and celebrations alike.
