Both are about female leads that have more of a dependent personality and runs into male leads that help them become stronger in their own lives.

Same type of plot line where the romancing starts in school and then moves on as they grow up. The growth of a group of friends.

Both has a controlling obsessive male lead (even though their characters are different). Both have a female lead that is outgoing, bright, and a act first, think later type mentality. The relationship between the main CP in both is CEO + worker.

Also with 3 older ladies as the mc. 3 different personalities but they are able to help each other figure out each of their lives. A little different from Iron Ladies is that fact that the characters in Fabulous 30 get more involved in their friends' lives where as in Iron Ladies, it is more emotional support than physical actions.
