If someone says that you resemble with Emma Watson or Scarlett Jahansson. How would you feel? (If you are a lady:P Perhaps for man, Ryan Gosling? )
I bet we'd all be thrilled unless that person didn't say it in a sarcastic or cynical way.
Though we need to love everything about ourselves and stop comparing with others, having a resemblance with a person whom everyone thinks of as beautiful or handsome feels good. In fact, we can find a lot of people resembling beautiful celebs that we see on TV and we can even find who ourselves resemble to!
Coming back to the point, being compared with people known to be beautiful or handsome feels great. Sometimes, for idols who didn't build so much reputation yet, being compared to the idols who made great success already may feel grateful. They may gladly accept the fact that they have resemblance with the big stars and at the same time show a charm of their own while being compared.
Fans found SoHee of ELRIS having resemblance with Irene of Red Velvet.
Meanwhile, YuKyung seemed to have a very close resemblance with DaSom, a former member of SISTAR.
Can you see the resemblance? Some disagree that SoHee and Irene look alike, but not many disagree the resemblance between DaSom and YuKyung!
