FASHION VS STYLE MAKE OVER

Many of my friends have made the New Year resolution of looking and feeling better and finding the direction to complete it. I'm very happy for them :)

We have had discussions and debates on what the choice is based on; what's it fashion (trend) or your personal style. Some even stated they do not see much difference between the two.

Second debate, do you persue fashion on you own likes, body or both?

Personally I know 'Image' is all relative, however I'm into Style as I think it defines your own personal character. From the colors you choose, to the cut and design. And I do think to look good, it should complement your body type. Plus any 'make over' can not hide inner changes as well. A makeover should bring a shift (positively hopefully) in body AND mind.

EX. One style I like is sporty, the brand names not exclusively important. So I can be in Adidas, Nike etc if they have items that I like. Plus having a positive mental attitude (PMA).

So asking for your POV with questions, and suggestions that I can pass along, on styles from grungy, classy, to femme (girly) not sure how to classify it. 

1) Should someone 'make over' into anything fashionable regardless of style and how it suits them?

2) Should someone have a style of your own? 

3) Or the oxymoron can one aim to be fashionable stylish? ;)
