Answer:
Star of Jude patches.
Explanation:
The 'Star of Jude' patches were small, yellow patches of fabric with a star of David as well as the word "Jude" (Jew in german) that Jewish people had to sew into their clothes in order for them to be identified by the public. This allowed for public shaming and discrimination as Jewish people were branded by the small patch. It was a law heavily enforced, even wedding dresses and formal clothes not permitted from it.
