Pair them with skirts
Try out some Indo-western fusion by complimenting the blouse with a printed skirt. A high-waisted skirt too could work well.
Even pants can work
If the blouse is short, stitch a border to extend its length and voila, you have a nice, cute crop top! This could match well with wide-legged pants.
Yes, pick those bling blouses and attach long fabrics of the similar texture to their bottom edge. With some additional attachments, you can have an anarkali or a long style kurti for yourself.
Traditional, of course
You can always drape a fancy saree around the old-style blouse or match the blouse with a trendy lehenga and choli.
