Blopper

Todays blopper , during bidaai shan was wearing his cream color blazer , but when they showed khanak imagining suraj saying her bye, shan was in brown (i guess ) blazer , so when did he get time to change his blazer alone ??

and one geniune q , why was khanak still in bridal outfit ?? does she have to be in same outfit untill she reaches her inlaws ?? ( i dont know so asking )
