Army jacket: Army Surplus Shop - similars: here, here or here (on sale). Faux leather skinnies: Trash & Vaudeville (try these, these or one of these). Clutch: Jerome Dreyfuss or try this or this one. Boots: Stella McCartney on sale here or here or similars. Foldable shades: Ray Ban
I highly recommend popping into your local army surplus and trying on a few. They're mens usually but makes them even better - more boxy and oversized. Good to contrast a slimmer lower half - read: hides your a**.
For the can't-be-bothered-with-the-hunt, I found some online (see above) that work and saves you walking all over.
ps. I tweeted yesterday being in the March issue of Lucky Magazine! and yes, I'm still sending copies to Mum back home. Check out another version I saw online here!!
