I just wanted to post a quick note on my trend observations during my hectic and haphazard trip to India. Also, Maya's post already answers a lot of introductory questions about traditional Indian garb.
Fashion and the adoption of trends is SO different from when I left India to come here 10 yrs ago. Today, the market for new global trends is the same as it is here and worldwide. I saw plenty of skinnies, leggings, banded tops, tunics etc. I don't have any pictures as my time out of home was hectic and not at all leisurely. I have to say, the girls there dress so much more smartly now than they did at my time there
The trends that were most prominent and widely embraced, though, were that of 1) ankle length leggings and 2) a variation of the salwars mentioned in Maya's thread called Patialas (India's own ancient version of harem pants :-D)
The ankle length leggings are actually longer, and hence more scrunched at the bottom. This is a perfect example. Leggings like these come in a myriad of colors and are being worn as comfortable substitutes to the churidar (tight salwar) that is going to be the bottom part of Maya's outfit. Churidars have always traditionally been wovens until now.
The patialas are more traditional in cut and style, but are being worn with long fitted tees/tunic tops by the younger and more trendy, instead of the traditional woven tops. They are sold in pairs: patiala + matching scarf (dupatta)
If I had time I would have loved to explore shopping in India, but my priorities this trip were different. But I did do what I enjoy more than shopping - spending time with my family
