f(x) girls performed on national Armed Forces Show recently.

Judging from the photos obtained,we can tell that the girls have performed "Lachata" during the event.However,there are a few photos which exposed members Victoria and Krystal's armpit to viewers.I am sure that the girls will have some laughs too after watching their own photos.

There are also some photos of the other members below,please have a look!Photos credits to Iheartfx!
