I ordered this top in black for my daughter. She usually wears a small/medium in tops so we ordered a medium and hoped that the reviews that said to size up were wrong. Well, that depends on how you want it to fit. The medium is true to size and is loose fitting on her. She is happy with it. The fabric is soft and has a nice stretch to it, which really does not make that big of a difference because of the fit of the shirt. We will order another top in a different color as well so that she can have an oversized one as well.
