I need advice ........ What to wear to the gym?

I know its probably simple but iv been going to the gym now for 5 months and i wear t shirt and shorts. I wear the shorts because i sweat alot, but an instructor told me i should wear a tracksuit top and bottoms. Actually wear under armour under neath the tracksuit and it would increase my weight loss and muscle gain. Is this true? It sort of makes sense but im really a beginner and its what he does. He also said to get a running suit with the breathable material or a heavy cotton tracksuit. I have seen body builders using all of these but as i said im a beginner.
Any advice would be great.
Thanks all.
