When Celine sent its first denim-on-denim look down its Spring 2020 runway in Paris last week, I interpreted it as a vivid harbinger for stylish outfits to come. Well, it's already arrived! None to soon, head-to-toe indigo has hit the streets of Paris, as evidenced here. Take note: jeans feature a new shoe-grazing length and straight-leg silhouette, like these by Slvrlake (I also love this wash), Moussy, Re/Done (also in this shade), and Grlfrnd. For denim shirts, the key is not too stiff and more p0lished than rugged. I'd go for these no-fail staples by Current/Elliot, Madewell, and H&M.

Just in: the French Editor uniform acquired an American twist: the white t-shirt. Naturallement, c'est tres chic! And, lucky for us, easy to emulate. The key lies in its fit and heft: slightly oversized, luxuriously heavy-weight and, perhaps most importantly, snow-white clean (i.e., not distressed). I like these new iterations from ATM Anthony Thomas Melillo, Bassike, Splendid (cashmere!), and Ninety Percent.

My favorite NYFW trend: the unbuttoned button-down. It's oversized. It's undone, both on top and bottom, and it's gorgeously paired with a bold gold chain like these by Laura Lombardi (great bang for the buck!), Rachel Comey (super popular) or Jenna Blake (forever-chic investment). I'd like to slip into these sexy shirts by Madewell, Toteme, Rails, Topshop, Vince, and R13.

After a dry cleaner mix-up when I received a Theory shirt instead of my husband's beloved Prada button-down, only one person was happy: me! Because I got a crisp, perfectly oversized blouse that I can wear all the time. Its relaxed, borrowed/stolen-from-the-boys silhouette is right up this fall's alley. (For the record, I tried to return the shirt to the cleaners but they insisted it had no owner they were aware of--perhaps a sign I should switch to another service.) Thankfully, for the rest of you, mix-up free, there are loads of desirable options out there that will undoubtedly make you happy from Vince, James Perse, Golden Goose, H&M, and Queen & Belle.

A friend of mine only had a minute to change out of her beach attire to catch a bullet train back to the city yesterday. When she re-appeared, 59 seconds later, she was wearing the cutest Rebecca Taylor puff-sleeve blouse (one I happen to have and is now on sale!) with jeans and sneakers. She looked perfect--and ready to go. Her presto change-o had me thinking that the puff sleeve top (i.e., a new fall must-have) might just be the answer to our hurry-up-and-look-cute quandaries--particularly helpful/strategic during the painstaking back-to-work transition. Other excellent options come from Isabel Marant Etoile, Ulla Johnson, Frame, Veronica Beard, and H&M. But wait, how cute is this one-and-done Asos puff sleeve jumpsuit?

I'm making the most of tank top time by wearing this season's freshest: narrowly cut on top, ribbed and fitted from H&M (in both black and white)!

I know, I know: fall is far, far away. But still. When an amazing fall find presents itself, I think it's worth at least some consideration. Especially when it's something you can wear it right now! Case in point: next season's must-have belted jacket. I'm contemplating whether I should snap up the do-it-all Stine Goya, above, or simply hit up H&M's low-commitment but highly-versatile version--and while I'm at it, pick up these key wide-leg pants and these faux leather wide-leg trousers to go with. But let's not forget: it's still summer, stylishly captured in these on-point possibilities from Opt (very Zimmermann at un-Zimmerman price!), Amanda Uprichard and Pamela Munson.
