It suits you.  LOOKS GOOD ON YOU.   
It suits Ann to be a grandmother.  SHE IS GOOD AT IT.
 
My shoes don �t match bag.  AREN �T EXACTLY THE SAME COLOR - SIZE - texture
 
I have a suit.  IN CARD GAMES - AS IN A PAIR - OR THINGS THAT GO TOGETHER
 
 
It doesn �t fit me. - too big or too small.
 
It doesn �t suit me.  - the style/shape is wrong for me - the color is bad for me
 
It doesn �t match my skirt.  -  doesn �t look good with the skirt because of color/ fabric etc.
 
 
Don � have a fit is this explanation doesn �t suit your needs.   fit- get excited/angry/upset
                                                                                     suit -  doesn �t answer your question.
