Hello! I've spent more time than I care to mention looking for basic t's and turtlenecks. I'm a healthy active rectangle, 5'8. Need something with stretch that isn't boxy, formfitting but not tight. Something thick enough to wear alone but layer able. I like my turtlenecks to fit snugly on my neck and I need some length in the waist/hip area. Can anyone help me get some precious time back by steering me to a good brand?
