Removing Borders from Hikashop

Hi There,

I was just thinking, alot of Hikashop looks quite "boxy" and I think that's because of the borders around certain features (Billing address, Shipping method, Payment method etc) makes everything look boxed in. I'm attaching an image to show what I mean.

Is there something in the Hikashop css to change the colour of all the borders to white, or does every feature have it's own css to style it, or is it this even a Hikashop issue and I need to look at my Joomla template?
