what meaning is the of "style"

I looked at the saw "Dowell Lifestyle Mall" on a plaque above on a building yesterday.  Is  "style" the same as "gangnam style"?

It is the same.

Style can be the way you do something.

Lifestyle=the way you carry out, or live,  your life.

Gangnam style= is the way Gangnam dances to the famous song.  He has a very unique style of dancing.
