It has a zipper in front and back lol xD work it guy!! Remember in the words of Gaga "looking good and feeling fine, slay" U'll look amazing and hot lol
Sorry, but I think this is for the bedroom & not a Gaga concert. I suppose it also depends on which country the concert is in. In Australia I haven't seen too many people wearing things like this. It may be different in your country.
Wear it with black versace skinny jeans or something!! Then you can feel comfortable showing up, it'll look amazing with the cut-out sides, and if you get hot or decide you'd rather just wear that- you can just take off the jeans!!? :)
