In the first episodes of the drama, the actress is seen wearing a lovely yellow cardigan. This is also the clothing she was wearing when Ji Soo falls for her at first sight. She looks gorgeous in this outfit.
We've looked up for the clothing and it is quite affordable. It is the V-Neck yellow knit cardigan (ALEKG006) from the brand LAP (Los Angeles Project).
It costs approximately 30,000 KRW or around 25 USD. You can have a look here for more about the product (Korean webpage). It is available in other colors too.
Did you also find this cardigan pretty? Is there any other clothing you are curious about?
