For reference, I am 5'3", 124 lbs, 32DDD/F, ordered size Small. This T is slim-fitting without being too tight. It accommodates my narrow shoulders and larger bust. The sleeves are the perfect length for me, and they are not too loose or too tight. The lightest colors of this T are opaque: no bra see-through. The best part about the T is the neckline. It's low enough to expose some of my short neck and it is not too wide of a scoop so that my bra straps show. More like a real crew T neck but without the super high neck (for that neck, see the Reiss style). The material is delicate but it does keep its shape with careful washing in cold water on delicate cycle and line drying on a clothes hanger. I am so glad I found this T. L'agence, please don't discontinue this style!
