Not from EG, but Gitman used that fabric in a shirt this season:
I wanna see someone in the jacket, shorts, and shirt.
Yeah, MAC has their entire spring buy in store, but a few pieces have sold out already (19thC shirt in Navy Floral for sure, maybe a few other things). Their buy is pretty wild this year... Tunics, aprons, some of the more out-there prints, etc. Their FWK pickup is really great too. Also, Bastille and Bloomingdale's have at least their first deliveries, not sure if/when they're getting more.
I could be wrong, but the houndstooth looks like it might actually be the Grey Strip Basket Weave, as seen on this Dayton shirt: https://www.thebureaubelfast.com/shop/1764/grey-stripe-basket-weave-dayton-shirt
Bastille in SF just got their 1st EG delivery, including that same Dayton, and the fabric is quite nice... stout, but soft and pretty lightweight.
