These are 100% mulberry silk at 19 momme. Momme is how silk is weighed, and 19\nis heavy for a garment: it is what stops underwear feeling flimsy, keeps it\nopaque, and lets it take regular washing without going thin at the seat.
\n\nThey are finished the way a good shirt is. The seams are French seams, sewn\ntwice so the raw edge is enclosed and nothing rough sits against your skin. The\nwaistband is elastic wrapped in silk rather than bare elastic, there is no seam\nacross the back, and there is no label to scratch. The fly is a traditional two\nbutton, and there are short slits at the hem so they move rather than ride up.
\n\nThis listing has always sold in a single size per colour, and the supplier's\nmeasurements are not published anywhere we can point you at. Rather than print a\nwaist figure we have not verified, we would sooner say so. Email us before you\norder and we will read the measurement off the pair we would actually send\nyou.
\n\nCold gentle machine wash with a mild detergent, no bleach, and a mesh bag if\nthey are going in with anything that has a zip or a hook. Do not tumble dry them.\nSilk dries quickly on a rail, and heat is the fastest way to shorten its life.\nIron on the reverse at a cool setting if you want them crisp.
\n\nSilk sits close to your own temperature rather than trapping heat, which is why\npeople who find cotton warm in summer tend to get on with these. If you want the\nsame fibre in a full set, the\nmen's mulberry silk sleepwear is in the same part of the\nshop.
