P. Jamas offers a beautiful collection of pajamas, robes, nightgowns, sleep shirts and other nightwear. P. Jamas only uses the finest, highest grade Egyptian cotton, spun in Switzerland and woven in Italy on old, slow looms that offer incomparable quality. Their pima cottons are the finest available and in the case of our knits, they make the fabric ourselve. The buttons for the most part are Japanese mother of pearl, the best there isâ¦and our needlework is extraordinary. This is one of our favorite sleepwear companies.
