I really feel the cold in winter and always wear multiple layers. My current long sleeved tops (from other brands) have become thin and are showing signs of wear so I thought I’d try these as a replacement. They are a great length so even with my long torso, I can tuck them in, and because they’re a bit silky, they don’t catch or grab onto my t shirts and jumpers when I layer them over. They’re also thin enough that they don’t add bulk but still provide warmth. If I have to push the sleeves up, they stay put and the cuffs don’t stretch out.
I haven’t found them to be particularly see through but then I bought them specifically to layer, so I haven’t worn them by themselves. I did size up to a large from my usual medium as I didn’t want it skin tight or uncomfortably fitted, and it’s still fitted but not restrictive. They are quite stretchy so you could stick with your normal size if you wanted it more fitted. Colour is a little darker/more muted compared to the photos, and certainly not what I’d call grape, but still a lovely colour.
