Basics serve as the backbone of every well-appointed wardrobe. While trending items like snakeskin leather pants and pastel fur coats may steal the spotlight (on Instagram and otherwise), affordable basics like seamless turtlenecks, classic outerwear, and timeless footwear often tie these attention-grabbing outfits together.

What's more, basics are always worth the investment. These classic pieces don't wax and wane with the trends and remain a go-to no matter what the season. The goal is to build a closet brimming with flattering, high-quality, and affordable basics that will last for years to come, and pepper in few inexpensive trending pieces each season.

Below, shop the affordable basics we're loving for 2021 and beyond.

Your wardrobe (and your wallet) will thank you.

Never underestimate the power of a great white T-shirt. This timeless staple—along with seamless turtlenecks, cozy cardigans, and a solid half-zip sweater—goes with virtually everything in your closet and will never go out of style.

Timeless outerwear like blazers, leather jackets, cold-weather wool coats, and denim truly bring a wardrobe full-circle. These timeless toppers are suited to every occasion, from work to going out to long-awaited special occasions in the future like holidays and weddings.

While '70s-inspired cords and animal-print pants will come and go, your favorite jeans and trousers will last a lifetime. Start with a pair of light-wash jeans, black jeans, or tailored trousers for work and dressier occasions.

Having a few flattering, timeless dresses in your closet makes holidays, baby showers, and job interviews infinitely easier—even on Zoom.

Start with a few solid black and white options, and mix in a few subtle patterns down the line.

Of course, accessories are what tie an outfit together. If you invest in a great pair of understated hoop earrings, black leather boots, a neutral purse, and a flattering pair of sunglasses, you essentially upgrade every outfit in your closet.
