I have been wondering who Ishita reminds me and it finally just clicked. In my opinion, her facial structure, those goregous dimples and cute smile are all similar to those of Kulraj Randhawa (think Kareena Kareena from ages ago on television and then later Punjabi and Bollywood movies like Tera Mera Kii Rishta and Yamla Pagla Deewana).
Check it out:
Both are wonderful actresses in their own right!
Cheers,
