One 2021 purchase that should have made my “Favorite Purchases” list (but didn’t; I have no excuse) is the Alice + Olivia Caleb Puff-Sleeve Sweater Dress. It is the ultimate elevated little black (sweater)dress, with perfect puff sleeves (done in a contrasting cableknit), a versatile mock neckline, and a fitted, flattering silhouette.
The ribbed knit, a wool blend (94% wool/5% nylon/1% elastane), is heavier-weight, and has plenty of stretch. Note that the material can attract lint, so avoid draping yourself in faux fur blankets (as I did on the day these photos were taken).
The dress has a pullover design so I’d suggest sizing up if you are in between sizes.

You can find the Alice + Olivia Caleb Puff-Sleeve Sweater Dress (sizes have become limited everywhere) at Alice + Olivia, Amazon, Bloomingdale’s, Neiman Marcus, Nordstrom, Revolve, Saks Fifth Avenue, and Shopbop.
