This is a 200gsm soft polyester tricot which has been given a cut and embroidered lace edge.  It is used for top cups, and normally you would just use the plain version for the bottom cups.  We sometimes the plain version (its called Panache), but often the shades are slightly different, so the surest way to get a perfect colour match is to cut the bottom cups out of the plain centre.  The lace is 19cm wide, the plain centre approximately 14cm wide.

Made in Switzerland in St Gallen.
