What is the meaning of "比一比" in 一件件新衣向身上比一比? Continuing from my previous question, here's another sentence I picked from a song.


  一件件新衣向身上比一比。


I tried to search through Pinpin Dictionary, it means: 


To make a comparison
To engage in a contest
To compare a little


which is rather odd and not making any sense to the sentence. 

I also think that "比一比" is a reduplication of "比", which could have the same meaning as "比比". I found one in Wiktionary, it means:


Everywhere; All over
All the time; Again and again


which has a better translation.

To sum up, what does "比一比" mean in this sentence? Could it mean "everywhere; all over"? Or do you have any other translation? Any help would be greatly appreciated.
比 in most context means "to compare" e.g. 比大小 (compare the size) 

But in the sentence, "一件件新衣向身上比一比" , '比' means 'to cling to or 'lie next to' (in order to compare or match)'

It is very common for a person to pick up a new clothes and  'cling' it to his body to check if the size and the style is for him

You can see it more clearly without reduplication of '比'

"把那件新衣往身上比一下, 看看大小是否适合"
