Long white T- shirts

[Dora26]

I use these to layer under short loose jumpers. Typically they are long sleeved and a blend of cotton and something stretchy. Anyway my current c 5 year old batch are getting past it and I can’t find similar anywhere….does anyone have any suggestions? TIA

Uniqlo or M&S

Ive been looking for the same thing for months. Those posted above look ideal except they are viscose. I have lots of lovely ones from White Stuff bought years ago. They are cut so well but are all in holes. I cannot find replacements as they are all cut in a boxy shape that is not flattering. The WS ones I have are cut to fit a woman’s shape.

Hush do them in stretch cotton.

H&M in their conscious cotton range are still nice for me after a year of regular washing.

You can't really beat Uniqlo Heattech. Got mine for years (not white though), they're so comfy, thin and warm at the same time.
Maybe not long enough for you OP?
