Allergic Bride
The lead protagonist of 12/24 Karol Bagh, Smriti Kalra (playing Simmi), had a very bad time recently due to heavy skin allergies. Smriti is highly allergic to any kind of metal and wearing heavy jewellery during her marriage sequence gave her skin rashes and allergies specifically around her neck.
Smriti's character is of a simple girl and requires her to wear only earrings, occasionally. However, as her wedding sequence was to be shot over a couple of weeks, poor Smriti could not bear up with the skin reaction and had to frequently visit the dermatologists.
