Placement of a word in a sentence

I am not sure where I can place the word "together" in the below statement. Which sentence is correct and why?

Mark and Phil wear frequently all the clothes we together bought from Landmark

or

Mark and Phil wear frequently all the clothes we bought together from Landmark

or

Mark and Phil wear frequently all the clothes we bought from Landmark together

Also, should the word "frequently" be before the word "wear"

Just for the context, Lanmark is the name of a department store

Thanks in advance
