I like to wear mine with a pair of loose-fitting sweatpants as I work, and if I’m stepping out, I’ll reach for high-waisted leggings. And because I always give credit where credit is due, I have to honor how well these wash: After four laundry days, they look exactly the same, and there’s no thinning or wear and tear on the fabric. The fit has also stayed the same, which I was concerned about since some T-shirts shrink in the dryer. To buy: $19 for two; amazon.com. A two-pack of T-shirts is just $19, and they’re available in 15 different colors, so there’s something for everyone. I prefer darker shades, so I grabbed the solid black and space dye burgundy pack.
