Re: Sari blouse..
I like the ones with zips at the back or along sides. BTW, the hooks don’t pop open if the fitting is right. I am thinking about getting a blouse made with puffed sleeves but don’t know whether I can carry that off or not.
Look here for some saree blouse designs ranging from simple and elegant to eccelctic. I don’t think many of them are wearable but you’ll find a few really good ones:
