Canadian brand Dace is on Swirl right now at 50-60% off. I like this sweater, $89 (was $220).
For those who can go to the Bird warehouse sale in Brooklyn, I envy you. For the rest of us, it seems like they have some of it online. I like this Tsumori Chisato t-shirt for $89 (was $356), and these Suno x Loeffler Randall sandals for $109 (were $460). There are some nice non-crazy patterned things on sale (here and here, for example) too.
The colors look a bit washed out here, but these grid-like Steven Alan shirts appeal to me more than the usual plaid. From above, $47, $63, and $71 (all were $158), at Tobi. Get an extra 15% off when you become a Tobi fan on facebook through August 15 (details here).
