I love V- necks. It is just the style collar that is most flattering on my face, neck and decolletage. For the longest time, all I could finds in a V-neck, was sweaters. I would wear them in the Fall and Winter, and then begrudgingly, give them up come spring. I am always hot, so sweaters were not a good Spring Summer choice, for me, even if I was to be inside, out of the sum. These T-shirts were the 1st decent fitting non-sweater V-neck I have found in Years. They fit very true to size, to shirt size. If you plan to wear exclusively under another shirt, you may want to size down. Okay, here's how I would describe the stay tuck, and why it's great for everyone. It seems like they were machined to not have be pre-stretched out at the bottoms, like most t-shirts are. It is not shirred. It just starts out fitting closer to your body than most T hems. Most T shirts are square on a hanger. These are slimmer at the waste. Great if you tuck, but even better if you do not. If you are going to wear it out, it IS a cotton t- shirt; I just carefully, while wearing it, stretch it to a custom fit for my waste. Then I do the same to my husband's. When we discovered these, we were both heavier than usual & not liking any clothing. XL men's looked like a tent on him, but he was too big for large. And, the exact same, could be said for me. These shirts in grey & black were just the ticket. If you try them, you will not be disappointed. As a matter of fact, my niece(who also loves them) and I discovered that if we see anyone in a grey or black T, that looks flattering on them, and we pay them that compliment, they tell us they are Fruit of the Loom "Stay Tucked V's or Tees. More colors would be great. But they are sliming, so if I could only pick 2 colors I would want black & grey. The grey is not heather grey. It is about the same shade of grey (in the sense of light to dark) as heather, but it is smooth solid color. Not something you see often. But again, when you see someone else wearing it, you notice it; not because you recognize it, but because it looks good & then, I usually realize I am complementing my own shirt. Lol.
