Just saw you were referring to the HF suits on RueLaLa, so I checked them out. These are definitely Lindsey model or similar (I have a navy one I picked up from BlueFly).
They are not mainline HF suits and do not retail for $1600, rather are made for discount sites and outlets. Easy to tell from the white label, lack of an interior pock flap, and lack of a pen pocket among other things. Other shortcuts are half-canvassing, plastic buttons, and lack of bemberg lining. All that said it's a nice suit with a traditional slightly slimmer HF cut and decent fabric. I think you paid a good price for a solid color suit.
