Angie found this fab turtleneck at Macy's last year:

I bought two - a black one and a gorgeous teal colour (which doesn't seem to be available with this year's colour selection). It's very comfortable, not too hot, and I like the ribbing on it because it has the same sort of camouflage-effect as ruching/pattern or what have you - it's forgiving and 'nice' to any extra flabby bits, imo - because of the texture.
In any case - I believe The Bay carries the INC brand - might be worth looking there to see if they might have these turtlenecks so you could give it a whirl.
Notes from me: size up in this particular turtleneck. Also - it's a bit on the short side, so not something you'd necessarily wear untucked with pants - depends on your height I think. Works beautifully tucked into skirts *and* worn untucked with skirts. For trousers, it works better tucked (imo and on me - I'm 5' 6" tall).
Next time you happen to be at The Bay - you might take a look and see if they have these there to try on.
