I know some of you ladies have tried "The Shirt" no-gap shirts by Rochelle Behrens (Sona and Una, I think). Do you have any size advice? By their chart I'm a small...but I'm not sure. I even called and spoke with someone at RB and she wasn't much help! She said in general the silk buttondowns run a little smaller than the cotton ones.

What is your experience? How does RB sizing compare to other brands?

Thanks!
