House of Harlow Keyhole Dress. One of my absolute favorite dresses — I literally own it in five colors because it's that flattering. The fit is amazing, and it's one of those dresses you can wear to pretty much anything. It's also adjustable, so it can accommodate a range of sizes and you can customize the fit to your body. I've worn this style for everything from weddings to dinners and nights out. Super easy to dress up or down!
