The RN number on this new old stock bra indicates that it comes from the Splendor Form Brassiere Company. I could find little information about this company, which no longer exists. They were located in New York and filed for a trademark in 1965, which expired in 1989. The bra is the classic criss/cross or crossover style with lace upper and smooth lower cups, lined with fiberfill. I wonder if this could have been a sample, due to the label not indicating the brand name and the size given in both US and EU designation (38B and 85B).
