Just putting in a good word for those tissue turtlenecks. They are an essential workhorse in my winter wardrobe because I layer them under everything--jackets, sweaters, short-sleeve/sleeveless tops, shirts--you name it. I don't size up since my regular size is a nice fluid fit, not too baggy and not too tight. I toss them in the regular wash and the dryer and have never had a problem with shrinkage or pilling. They come in a host of colors and stripes. And (this is a big one for me) the turtlenecks don't fit too tightly so they stay scrunched down around my neck. I wasn't blessed with an overly long neck, and age hasn't helped in this regard, so too many T-necks are off limits because they look like they are swallowing me whole. These are just perfect. My only caution is that they are light-weight cotton so they may not suit those who are looking for a substantial T-neck that can serve as a thicker outer layer on its own.
Can you tell that I think the orchid one ought to come home with you? I have it and the color is a real pick-me-up this time of year.
