she's right.
See if it's at all possible to try them on (at nordstrom, etc.). They really do all fit the same. I've only ever sized up for ONE pair, and even then I could have gone with my regular size just it would have been tight. Once you find out your LC and HH size (mine are the same) and figure out which style you prefer, your set. I don't think twice before getting paige off ebay, as long as it's a size 26, because (for once) I'm so firm with my size that it never variates.
It is, unfortunately, really hard to the find the ones you want at nordies rack. When I'm there they only have bigger sizes, but they did have one pair of crops but I already had them. You just have to be REALLY diligent there if you want to find a pair. But your best bet is ebay. If you can find good deals, it should be easy enough to resell them if they don't fit (but really this shouldn't happen if you know your size). You could buy from online retailers, using there coupons or something, but that's just an awful lot of money that really isn't necessary (IMO) when you can find the same exact thing on ebay for a lot less.
and to your last question, yes. I've never gone wrong, my size is my size.
