Is "under-wardrobe" a thing? It should be. And these things are the best. They're amazingly one-size-fits-all and they're long on my torso, which is essential for this 5'10" body. They're perfect tucked in under a blazer or left long with leggings and a long sweater.
And speaking of leggings. I have a pair of Tina's in gray and in black and I wear one of them at least once a week. They're pricey, but they're totally worth it.
