OBSESSED with these tees. Great fit, great quality, great value. I ordered a size M initially (I usually wear a true M in tops w a 34DD chest) - when I tried the M on, it did feel a bit oversized, but I still loved it so much. I then ordered two more of these vintage tees but in different colors and both in a size SM to feel for that size on me. The SM fits perfecetly, but ironically, now I prefer the size M. All this to say, both sizes work great, just depends on what look you are going for! Either way, these tees will now be a staple part of my wardrobe. I hope that Mate offers these tees forever, so I can continue to shop it in the future when it's time to replace this collection that I will for sure wear a ton!
