Yossi asks:
IT IS BROUGHT IN THE GEMARA AND RAMBAM THAT WIVES USE TO WEAR SPECAIL CLOTHES TO SHOW THEY WERE A NIDA --SO EVERY ONE IN THE TOWN WOULD KNOW WHEN AND WHEN SHE WAS NOT A NIDA IS THIS NOT A LACK OF TESNIUTS( MODESTY)
The Kollel replies:
In general, the women did not go outside much in those days, especially when they were not Tahor. The Gemara does mention that the neighbors knew. However, Tzeni'us is required to hide the time of Tevilah and relations, but not to hide the opposite.
