When you put 'only' at the end of the sentence, it is for emphasis, which is sometimes appropriate. As for the third sentence, "I wear only silk pjyamas" sounds like you do not wear any other clothing than silk pyjamas at any time of day. The first sentence is the most common in this case (Subject + adverb of frequency + verb... for present simple verbs that are not 'to be'). Is that clear?
