Thanks for putting up a great review. Victoria's Secret is one of the most raved brand. I'm not into fragrances much but I have been meaning to get the Bombshell. Let me know if you have to say something about it too.
About the availability in Pakistan, there are no as such trusted physical stores of International stuff except The Vault at Emerald Tower 3 talwar or Vegas in Islamabad. But there are numerous authentic online sellers on Instagram.
