She’s the arbiter of French cool and she's even gone so far as to convince us that our sneakers should come with a wedge heel. Now, big news: This highfalutin designer is going mass.

Introducing Isabel Marant for H&M.

Available tomorrow--online and at select stores nationwide--this buzzed-about collection oozes Marant’s inimitable style but at a price point you can expect from the people who brought you a $3.99 T-shirt.

But take note: This isn’t your average Target-esque collab (i.e., utter chaos). H&M has set some hard-and-fast rules for shopping the collection. For instance, online shoppers are limited to one piece per customer (we’ve got our eye on that dress). If you plan to be one of the folks standing in line outside the store, you’ll need to wait for a bracelet before you enter, and then you'll be allowed to buy only four items. Meaning there’s no chance anything will be left by 5 p.m.

Head over to the slideshow to check out our favorite pieces from Marant’s H&M collection, plus a few uncanny comparisons to her runway looks.

And tomorrow, be sure to wear comfortable shoes.
