Tankish, unarmored bard?

Hey guys!! So I had this idea for a character that emphasizes vaudevillian, slapstick style antics and durability (ie over-exagerating hits, leading trips into tumbles) and I wanted a way to make this. Multiclass should be fine, but I did wanna keep the unarmored aspect pretty intact. I figured college of dance would be good, but if you guys have any recommendations, I'd love to hear em! Also, maybe some way to keep hits coming toward me instead of my allies could be fun. 

Tankish and unarmored points much more to barbarian or monk.

Barbarians get huge hit die, and are strength based so can take Farmer background which gives them Tough origin feat, for +2 hp per level. Rage lets them resist damage.

Monks get Deflect Attack which lets them completely dodge attacks up to a certain level, every turn. They dont get as big a hit die. And Farmer background doesnt let you increase dex, so you dont get those extra hitpoints from tough.

Trips and tumbles require weapon masteries like quarterstaff/topple. I dont think bards get weapon masteries? Not sure about monks either. Barbarians do for sure.

"some way to keep hits coming toward me instead of my allies could be fun. "

One way to do this is to grapple an enemy. If you grapple an enemy, they attack anyone but you at disadvantage. Grappling is purely a stregth based thing, so you'd want to go barbarian. Path of the World Tree really helps with grappling. You can teleport an enemy to be next to you, set their speed to zero for a turn, which gives you an opportunity to grapple and punch them. 

When you do an unarmed strike you notmally choose damage OR grapple. But grappler Feat lets you do both.

If you really want a bard, then you wont be as tanky, and you wont be able to grapple as well as other classes.  You can be more support to help players avoid damage. The Musician origin feat allows you to hand out heroic inspiration during a rest. That can help everyone avoid one bad roll of any type.

Instead of grappling, you could use Hold Person spell. At higher levels, battlefield control spells like Wall of Force can keep the baddies away from your friends.

Bardic inspiration helps with particular rolls. 

And you can pick up healing spells.

dance bard, the unarmed strike is strong.

 also the 14th level feature is posibly the best non-spell tanking feature
