Plus size white boatneck T-shirt, 3/4 sleeve

NWT or NWOT or great/excellent condition white T-shirts with three quarter length sleeves and boatneck neckline (basically straight across throat, front and back. All one color, knit may have some stripes or other variation in knitting as long as no other colors are visible; Prefer cotton rayon blend but 100% cotton is OK or a bit of poly or lycra with the other elements; must be opaque, no lace. I have occasionally seen some that have a neckline trimmed in navy or black that would be ok.
