Bogus Question from a Lady Kendoka

Hi all,

I'm new to Kendo and wonder if any ladies could help me out with my do issues! I'm using the equipment at our dojo so it's not mine (which might be the issue).

I've got a pretty small waist and wide hips so my do basically just sits on me. Whenever someone strikes my do their shinai seems to glance down and inevitably whack me on my hips. I'm coming away from every session with some pretty nasty bruising on my right side.

Is this normal? Am I just being a sissy baby? Or is my bogu completely wrong for me?

Thanks in advance!

Edit: Cheers to Autocorrect for the obnoxious title! Meant to say Bogu!
