Tina Fey and Amy Poehler's tacky dress fail in Sisters trailer: 'It's a lot of under-teet'

The first full trailer has finally landed for Tina Fey and Amy Poehler's new comedy Sisters…and it was well worth the wait.

See the comedy duo's NSFW shenanigans, tantrums, tacky fashion faux pas and dorky dancing in the teaser above.

The former SNL co-stars reunite in the flick from Pitch Perfect director Jason Moore, playing disconnected siblings summoned home by their parents to clean out their childhood bedroom.

Looking to recapture their high-school glory days, the sisters throw their old classmates one final party, which turns into an epic rager. 

Sisters hits Aussie cinemas in 2016. We can't wait that long!
