similar concepts of the boy leaving his home to go into fashion

Both shows are centered around the fashion industry , and main characters who are wronged in some way bu someone close to them.

Both revolve around making clothes...in both the female lead always competes with the 2nd female lead who tries every trick to win!

- both are about a rookie entering the fashion world
- baby faced beauty has elements of romance, while Underwear does not
- the female lead in Baby Faced Beauty is a lot older than the FL in underwear, and she had her mind set on clothing design

Both rom coms are about a younger man falling for an older woman. In Baby Faced Beauty, the story is more about her professional growth-- whereas Oh My Lady is more about the male lead's personal growth.

Both stories show younger men falling in love with older women. He is "forced" to pursue her for deceitful reasons in the Last Cinderella, yet ends up growing more mature and responsible. In Baby-Faced, the younger male lead sincerely helps the female character grow professionally.

Both dramas deal with the female lead growing into herself/finding herself. Also, in both, the female leads have to deal with a hostile working/school atmosphere, are faced with being older than everyone else and have family that doesn't support her dream.
The male leads in both are sweet and funny, not like the usual jerk leads. Finally, both dramas are light and funny, with a lot of heartwarming moments.

Different story plots, but both are funny romantic comedies about unmarried spinsters that tell a lie which jeopardize their jobs
