This is our most frequently asked question! While 100% silk is synonymous with luxury, it is naturally a "cool" fabric, which can feel a bit chilly during autumn and winter. For our Thick Silk Pajama Set, we specifically engineered a blend of Mulberry Silk + Viscose + Specialty Warming Fibers. Here is why this blend is actually superior for colder months:

1. Enhanced Warmth Retention

Pure silk is thin. By adding Viscose and warming fibers, we create a "thermal layer" that traps body heat much more effectively than single-layer silk. It keeps you cozy without the bulk of a traditional fleece pajama. 

2. The "Silk Touch" Remains

Don't worry—the part that touches your skin still carries the iconic smoothness of silk. The blend enhances the weight and drape of the fabric, giving it a rich, buttery feel that stays elegant even after a long day of lounging. 

3. Durability & Anti-Static

Winter air is dry, and pure silk can often suffer from static cling. The inclusion of Viscose (a natural cellulose fiber) improves moisture absorption and significantly reduces static, while making the set more resistant to pilling and easier to machine wash. 

Summary：Our Thick Silk Collection is designed for those who refuse to choose between elegance and warmth. It’s the luxury of silk, upgraded for the winter.

Our pajamas are designed with a relaxed, comfort-first fit. We generally recommend choosing your standard size. However, if you prefer an extra-roomy feel for sleeping or are between sizes, we suggest sizing up

Wrinkling is a natural characteristic of high-quality silk blends. Simply hang them in your bathroom while you take a warm shower—the steam will naturally smooth out most creases. For a crisp look, use a garment steamer on the lowest setting.
