This is the cutest "Hillwiew" denim overall dress from Madewell. Size 12. Style F5173. A little stretch makes this so comfortable! "Made of best-of-the-best denim with a comfy bit of stretch, this jumper-style dress looks just as good layered over a tee as it does worn solo. Night-out overalls, basically." Measures approximately 19" from pit to pit and 36" in length (adjustable). In great, gently used condition. If you have any questions, please let me know!
