I believe in investing in wardrobe workhorses that you'll have for years and years. I have an arsenal of incredible luxury knitwear bought second hand from The RealReal. That said, I also love a good high-low mix in my wardrobe, and H&M has stepped up their sweater game this season with some very affordable knits.
I own both colors of this $29.99 Rib Knit Cardigan (size small). I highly recommend this cozy knit for fall! Styled here with Green Gold Topknots and a custom charm necklace on our gold-filled chunky chain.
I also can't wait resist a good blue and white striped sweater. This nautical pullover is classic. Impressed by the quality. Get 'em before they are sold out!
