Why, oh why did you post that link to Nuu-Muu, Jesse?
I have been restraining myself from buying the Terry tunic, as it looks like a long version of the Eurohalter, which I love. I am not sure if I'd wear it riding, but I would certainly wear it around town.
I like the idea of the dress that I can wear my own bra with (nothing, ah, showing), but I think the Nuu-Muu might be too long for me at 5' 1".
