As the outerwear of choice for generations of detectives and film-noir heroines, a good trench transcends practicality — it’s something both romantic and completely mysterious. Remember the climactic moment in Breakfast at Tiffany’s when Holly Golightly and Fred kiss passionately in the middle of a torrential downpour, both in their beige trench coats? Or Catherine Deneuve in Les parapluies de Cherbourg? Inspired by classic film (and April showers), we took on the challenge of finding the best trench options currently on the market under $400 — each with classic silhouettes, neutral shades, and of course, good value. We test-drove a selection from Uniqlo, Zara, Trademark, and Brooks Brothers in pursuit of the perfect, classic trench. Click through our slideshow to see the results.
