Mu kal clear ho sakte teh ya nahi ?

I bet kal sare mu clear ho sakte teh bcoz when kamala and vittal decided to take cloths for sammy ,ring etc .and they did shopping too but million dollar question is ?
1. Agar dress liya toh kiss ke size ka ?
2. Ring also same kiss ke size ka ?
Raghav ko kalpi ke size ke liye they explained us with pakhi ko ring phenaya but here my question is raghav ko kaise pata hai ki dono ka size ek hi Hi. ya phir ragav itni baar kalpi haath pakkad kar yeah andaza hogaya hai ki dono ka size ek hi hai 😉 and now kamala ko raghav ki pasand ke baare mein paatha hai OK understood magar kamala ko size ke baare mein bhi pata hai 😉 .still mystery to me 😲
