So. I'm on the cusp of plus size. I tend to wear an XL if the item is knit with no buttons involved, but I size up for button-down blouses. I have a couple of no-iron white oxford shirts, but I'm looking for something more like a shell. But not a shell because all the ones I've tried are quite translucent. And I don't want to wear a cami. I want a substantial pull-over-my-head blouse with short or no sleeves that can be worn tucked or untucked, dressed up or down, and is comfy. I feel better in white, not ecru or winter white or ivory. Can anyone point me in a specific direction? I've tried on the usual suspects at NAS and none of them are quite right. I have a great top from CAbi that fits the bill but it's been a workhorse, and it's time to retire it.
