Of course, but this is only a healthy transformation if it allows you to still maintain your core.
Differences in style should not look to change you. They should enhance you or add to your personality.
That said, there are times when we want to be or feel different..
Eg. when dressed up and going to a formal dinner vs pulling on our favourite clothes and hanging out with a best friend.
All of this is part of the flavours of life and what makes living so wonderful!
