We actually have no idea if the hats were “as represented”, seeing as OP did not post a photo of them.
It is entirely possible that she is mis-remembering the hat that she saw on someone else’s head over 8 months ago. I am guessing she did not go up and feel the hat on someone else’s head, to gauge quality, and color is all relative depending on lighting conditions and age…maybe that rich chocolate hat she saw at Devon was a few years old and sunbleached.
I know lots and lots of things look better on other people than they do on me. 
Personally, I’m willing to give the company the benefit of the doubt, in that they didn’t ship out two sub-quality hats just to ruin the OP’s Valentine’s day.[/QUOTE]
She doesn’t even need to be misremembering the hat. Colors look different depending on the light and even the colors around them. (Artist here.) So what she perceived as a certain shade of brown when she first saw the hat could look very little like the brown she saw when she put the hat on her own hair in her own house under different lighting. Unfair that colors can be so tricky! 
And as you pointed pointed out, the original wearer may have looked a lot better in the hat than the OP. Different sized head, different shaped face, different hair, etc. All could have led to the original hat looking a different size and shape than the one the OP received - and yet, the hat could have been the same. So it goes.
