LG Shark Skin suit = Swim Skin suit?

I have been meaning to buy a skin suit for the swim (Blue 70 etc…). Right now I race in an LG Shark top and bottom, is that a swim skin suit already? I never really thought about it until Buffalo Springs. That suit plus a wetsuit that really stuck to me made breathing a bit interesting to say the least.

I have an olympic, non wetsuit race coming up and I am looking for every advantage I can get in the water
