To start - I hate buying clothes online.  I tend to have bad luck with or without sizing charts involved!  I was so happy when these pants showed up super fast, and fitting just like I had hoped they would.  These are the kind of pants you could dress up or just look comfy cute in, at 5'6" I found them a little long, but if you like rocking a heel, they will be perfect.  To help with sizing, I wear a 14 in jeans, I am all curves, especially through my hips.  I purchased the 18/20 to be safe, I'm glad I did.  While I think the 16 may have fit as well, (they are very stretchy pants) I won't be worried about any shrinking in the wash this way.  As a previous post said, these are very flattering and super comfy.  All in all quite pleased so far.
