This outfit ticks so many boxes for me....timeless, classic but a little-bit-sexy (do you note the tinest bit of bra* peeking out of her shirt? and the little ankle zippers on her jeans?), all of the pieces can be worn summer or winter (take off the tights and maybe the blazer for summer, or replace the shirt with a crisp white tank when it is desperately hot; add a cape or coat for winter), and everything will still look good (provided you don't fluctuate too much in weight which, of course, the Parisian woman does not!) for years to come. Parfait!
