if you already have both costumes unlocked (its an account wide unlock) on other toons. then it doesn't show up as a reward anymore.
If that ISN'T the case. i advise you opening a support ticket so they can look in to it.

They were also sold in the crown store at one point and may have been in crown crates too, so you could have gotten them from there.
Your post is a bit unclear so I'm going to cover some of the non-glitch possibilities to get them out the way:
1) What level was your character when level rewards were introduced? They aren't given retroactively so if you were above level 20 you'll have missed it and will need to make a new character to get it. (3 new characters if you want all 3 costumes.)
2) Did you already have one, two or all 3 of these costumes unlocked? If so they don't show up again. Same with anything else which goes into Collections or which you can only get once, like the crown crates. If you've already got it then it's just not mentioned.
(The level rewards definitely do still give you a choice of costumes at level 20, I just picked up the Mages Guild robe today on an alt.)
