Re: Eagle eyed fashionistas....
Haha when I was younger I used to wrap my mom's long dupattas and shawls around my body and sling one palloo over the shoulder as well to attain the sari effect, but only did so at home. Wearing that out in public, ermm... I dont think its a good idea.
As for your paishwaaz, its so gorgeous why do you wanna cut the sleeves off?! I think long sleeves look really nice and classy... you look great with the full sleeves in the pic you posted.
Keep everything as is! If you wanna do something with your dupatta, maybe get one of those vest type things made and wear it over a plainer suit in a similar color... and youll still have enough material to keep it as a dupatta.
Just a thought, I dunno im no designer! shrugs
