How to Care for Your Silk Underwear — A Complete Guide
Silk is more resilient than its reputation suggests. It simply asks to be treated with intention.
There is a persistent myth that silk is fragile — a fabric to be handled with anxiety, kept from water, and never trusted to anything but the most cautious hand wash. The reality is more straightforward. Silk is a strong, durable natural fibre. It has been worn by civilisations for thousands of years precisely because it endures. What it asks of you is not difficulty. It asks attention.
This is your complete guide to caring for mulberry silk underwear so that it lasts, maintains its lustre, and continues to perform at the level you bought it for.
HOW TO WASH YOUR SILK
Hand washing is always the preferred method for silk. Fill a basin with cool or lukewarm water — never hot, as heat degrades the protein structure of silk fibres and causes shrinkage. Add a small amount of silk-specific or gentle wool detergent, and turn the garment inside out before submerging it.
Gently agitate the fabric in the water for no more than two to three minutes. Do not scrub, wring, or twist. Silk does not respond well to friction — the same quality that makes it so comfortable against skin means it is sensitive to aggressive handling.
Rinse thoroughly in cool water until the water runs clear.
If machine washing is necessary, use a mesh laundry bag, select the delicates or wool cycle, and use cold water only. Keep the spin speed low.
HOW TO DRY YOUR SILK
Never put silk in a tumble dryer. The combination of heat and mechanical agitation will damage the fibres irreversibly.
Instead, remove the garment from the water and lay it flat on a clean, dry towel. Roll the towel around the garment and apply gentle pressure to absorb the excess water — again, no wringing. Then unroll, reshape the garment by hand, and lay it flat or hang it in a shaded area away from direct sunlight.
Direct sunlight will fade silk over time and weaken the fibres. Shade is always preferable.
STORING YOUR SILK
Store silk away from prolonged light exposure, ideally folded rather than hung — hanging can cause fine silk to stretch over time at the suspension points. Keep stored silk away from cedar balls or strong-smelling deterrents, as silk absorbs fragrance readily.
STAINS ON YOUR SILK
Act quickly. Blot — never rub — with a clean cloth and cool water. For more persistent stains, a very small amount of gentle detergent applied directly to the area and left for a few minutes before rinsing is usually sufficient. Avoid any product containing bleach, enzymes, or brightening agents, all of which will damage silk.
WHAT TO AVOID WITH YOUR SILK
Perfume and deodorant are the most common causes of silk degradation over time. The alcohol in fragrance and the actives in antiperspirant both react with silk protein and can cause localised weakening or discolouration. Allow both to dry completely on your skin before dressing.
THE REWARD FOR YOUR ATTENTION
A well-cared-for pair of mulberry silk boxer shorts will not just last — they will become better with wear. The silk softens and conforms with use, becoming more personal over time. This is the nature of quality materials: they do not simply hold up. They improve.
Treat your silk with the same intention with which it was made, and it will return the favour for years.
