All I want is a white, cap sleeve, crew neck, petite, NON-SEE-THROUGH t-shirt.
I'd pay up to £20. Does this unicorn exist anymore?
Ten years ago, M&S were my go-to, but I looked at some in there today and they were so see-through that every bit of the hanger was visible. BHS did fantastic ones but they're long gone and Lands End's ones did the job for a while, but this year's batch are about a foot too long, even in petite, and appear to be cut for a brick body shape.
Dorothy Perkins, Gap, Boden, Next, Teespring, and Cotton On all also seem to specialise in hello-and-have-you-met-my-bra white tees, sigh.
