Not sure what size I should get . I wear a medium in ladies shirts

Should I get a extra large if I wear a mens large, and are the pips and communicator removable?

The female version isnt in come in plus size. i am a l in mens but an xl im womens very busty. does this costume work for women or is it tight chested

Do you have extra small size?
