Also beginning in 2019 tourists are allowed to go without an Abaya, at least officially. And apparently in some cities more than others it's at least somewhat common to see women without. Jedda especially it sounds like? Still very much the norm though.
Clothes were another concern. Though foreign women are no longer required to wear an abaya (robe) by law, I was uncomfortable not wearing one. Outside of Jeddah and diplomatic areas of Riyadh, I did not see any women without abayas. Most women also wore hijabs and niqabs. In villages and towns, despite wearing a hijab, I still stood out because I didn't fully cover my face.
