If I were to take levels of Monk and Barbarian would my AC be 10 + Dex + Wis + Con or would I have to choose either Con or Wis?
I think the rules read strictly as saying that you use whichever you got first. From page 164 of the PH:
"UNARMORED DEFENSE
If you already have the Unarmored Defense feature, you can't gain it again from another class."
Personally, I'd allow the player to use whichever was higher (or the barbarian one only, if they used a shield). One of the comments the D&D designers often use is "It's not going to break anything" and I think that applies here - as a general guiding principle, I try to maximise access to PCs' class features.
barbarian monk
barbarian monk
barbarian monk
no matter how many times you say it, it just sounds silly
the character idea was a Red or Gold Dragonborn Monk who at some point in the story losses his cool and his draconic blood comes to a boil(when he takes his first of many levels of barbarian)

ah thank you, i was going off the srd and i hadn't found that part
There was FAQ on the D&D Homepage about AC.
Basically, in 5E, different sources of AC do not stack. AC in general is a static amount.
For example, barkskin gives you an AC of 16. It does not give you an AC bonus of +6. It does not give you an AC of 16 + your Dex modifier. It's just a flat AC.
Likewise, a lot of sources (monk, barbarian, dragon sorcerer, mage armor) give you an AC of 10 + Dex mod + their special thing TOTAL.
Unfortunately, you can't make a barbarian/monk/dragon sorcerer and get an AC of 13 + Dex + Con + Wis.
But that would be cool.
