I don't think I would spend that much on a tee, which is often a layering piece for me, and a casual one at that. Tees always seem to lack longevity, due to wear and tear, as well as poor quality. Most of them are too sheer for practicality these days as well.
I'd go higher than usual for a magic one, but for the limited role they play in my overall wardrobe, these numbers wouldn't make sense. I am thrilled I found a gorgeous black silk tee at the Rack for a complete steal. I would have paid more the versatility and elegance of that one.
Agree that this is a courses for horses question. I have splurged on many items, yet there are many more that I would never consider. One person's single purchase is another's seasonal budget. That's what I like about YLF- so many approaches and options, all leading to enhancing personal style.
