This fall I have been completely obsessed with my long vest (or sleeveless trench, long waistcoat, whatever you want to call it) from Zara. I'll admit though that when I bought it, I wasn't exactly sure how to wear it. With jeans? With a dress? Long sleeves underneath? At home, I tried so many different variations and I quickly realized that I liked them all. And it even doubles as a dress! This might be one of the most versatile layering pieces I own and has now become a wardrobe stable. It instantly updates any look and the loose fit is really flattering too! It draws your eye to your waist giving you a long and lean silhouette. There's definitely a cool girl factor to this statement waistcoat. Not sure if you're like me, but sometimes I think to myself, I'm not cool enough to pull this off. Well I promise you that you are! It feels very effortless. It's like getting to wear your favorite jacket indoors! My recommendation is to opt for a solid neutral (like beige, camel, grey, black or military green) to pair it with more outfits in your closet. So if you're looking for a key piece this fall to in-vest in (pun intended! See what I did there! Hah) then I suggest the long vest. Lately I've been eyeing all these winter sleeveless coats. Which officially makes the long vest a year-round must-have! Here are a few inspirations on how to wear it!
