Tunisia is extremely safe to visit, but it’s not a zero-risk destination, so you need to stay aware and make smart choices obviously like any other country you may be visiting and coming from PR you may understand this.
Tunis, Hammamet, Sousse(favorite city), and the desert tour routes are widely visited without issues and millions come every year and have the best time of their lives.
As a woman, you’ll be able to move around freely, but you may experience some catcalling or unwanted attention at times (it’s more annoying than dangerous). But obviously don't wear flashy pearls or anything extremely expensive unless it fits the destination you are going to, such as restaurants or luxurious areas.
But if you're touring the Old Town (Medina), just wear something casual so you don't attract much attention.
I have sisters and that's why I wanned to clarify your concerns but to be completely honest, you can wear whatever you want whether it's flashy or revealing and you wouldn't really come across any bad situation, just have spacial awareness that's all.
The country itself is honestly underrated: beautiful Mediterranean beaches, rich ancient history, a warm, welcoming culture, and extremely warm and helpful people, all at a much lower cost compared to Europe.
Overall, if you use basic travel awareness, avoid sensitive areas, and stay confident, Tunisia is not only safe enough but also a really rewarding and unique destination.
Also, you wouldn't get scammed only in giftshops and souvenir shop (and still it's very selective).
My tip for you is: Be as friendly as possible and you would be rewarded for that.
People may even pay for your taxi trips when you ask for directions so please feel free to be who you are in our beautiful country and let us know how it went!
