I was fully prepared to commit a major SYC infarction. One of my favorite local boutiques was going out of business and had everything 50% off. But the sale started two days ago, so by today most of the store was cleared out. I bought nothing.
I did poke my head in another boutique that sells Etoile Isabel Marant. They had this coat for cheaper

But the largest size they had was a 40, normally I'm a 42 in this brand. The fabric and color were really nice, and the 40 fit, even over my puffer vest. It wasn't an oversize fit though. I'm not sure a 42 would even fit like I want it to.
