Quality vs. Sezane: They use a lot of the same synthetic materials like polyester and viscose but they don’t have as many natural materials as Sezane​,​ like silk and cotton. I do think the quality of Sezane pieces is a bit better but the style of Rouje pieces are really lovely. I have a hard time buying from them directly because their shipping and returns are very expensive​,​ so I mostly buy from the secondhand market. Rouje Sizing: I’m pretty solidly a 36 (US 4) in Rouje and a 34-36 (US 2-4) in Sezane. So I’d say it runs a tad small but it is fairly consistent.
