Best stores in Islamabad for ready to wear and luxury pret?

I have lots of family in PK so can get clothes made but mom is making a quick trip only to Islamabad and don’t want to bother her with darzis. What are the best ready wear stores in Islamabad, where she can get pret and luxury pret? Not lawn. I know Sapphire and Agha Noor in Centaurus, but do any other designers have Islamabad outlets?
