Ok dont laugh, but i kept a tikka on with eyelash glue hahahah (this is what a make up artist does when she gotta improvise lol) and even saw the piece to the actual chunni. we were out of pins cos of the chunnis but... it worked for the performance at least. Im just not sure if its gonna be a cheap option cos eyelash glue it kind of costly.
a thing Ive done for weddings and all, I make a little puff on top of head and behind it a tight french braid, then clip the tikka (you only need a clip or two cos it attached to the braid) and then hide with the hair piece at front. Then put chunni normally...
About long skirts for girls i ironed the piece i wanted to take out and saw it. It looked kind of fluffy at the bottom, but we didnt have time to fix it. you can also roll it at the top and pin, i did this with a flamenco skirt hahaha and it was fine cos it was hidden by some hip scarf, but yah if your kutas are long enough and baggy enough...why not?
