I jumped on the Dad Tee bandwagon a little late, was my first purchase of one was recently and it was this color, all i have to say is Oooo Mmmm Gggg!! i have never come across such a soft comfy t-shirt, like i know you must think "but it's just a t-shirt", i thought the same, but you just have to try one & you will be hooked. It's literally my go to, i cannot get enough of it. I have washed it and its just like new. I'm hoping she restocks other popular colors because i need to add them to my closet. I'm more on the thin side on my upper body, i'm 5'5 and usually between S & M. For this particular top i ordered a Small, a M would of been a longer, looser type of Tee. I'm almost certain and xs would fit as well, may just be a little more fitted. You really can't go wrong on the sizing or style !
