crop of X-Force vol. 1 #50 focusing on the women characters on the back cover with cropped focus on Boomer (Boom Boom) who has a tiny torso that is off-set a lot from her neck and shoulders and bent backwards to have her butt thrust out at 90 degrees
crop of X-Force vol. 1 #50 focusing on the women characters on the back cover with cropped focus on Domino standing back to back with Siryn, Siryn's body is mostly blocked by a giant gun Dominoi is carrying which is hiding her waist, but it is clear her waist is tiny behind it from how her body is going into it like a triangle and her hips and butt are offset from where her waist is by quite a bit

Yet More Worm Girls

You can't see Domino's waist because of that giant gun, but I assume she looks as much like a mantis as Boomer does.  Or one of those aliens from MIB.
