Actually the same happened to me. I bought it because I thought these pictures represent what you'll look like after buying it and to support the devs, because I think they are doing a fantastic job.
Turns out that I won't actually look like that because vital parts are missing (for example the sun glasses). Well, it's probably my fault for not paying enough attention and read the entire description. Yet I think it is somewhat misleading and leaves a bitter taste of deceit - for the sun glasses being prominent in these pictures.
I think they should at least mention IN the pictures, that they don't actually represent the actual content of the DLC. Kinda like the serving suggestion on packed food - because that's just not how it will look anway.
