how tight?

[fizz-tally]

go you have your best girths/plates?

I X-country with a leather hunting brestplate and fit it with four finger space between breastplate and shoulder/chest. Don't know if that is 'correct' though,

but doesn't rub or restrict her movement, and saddle has never slipped.

Guess fitting will depend on the type of brestplate though.
