Changing border thickness of "MaterialDesignOutlinedDatePicker"

[washburnit]

HI,

how could I change the border thickness of the control in the subject?
I've set the control as follows:

<DatePicker Name="dtLavo" Width="180" Style="{StaticResource MaterialDesignOutlinedDatePicker}" HorizontalAlignment="Left" Margin="20" mdix:HintAssist.Hint="Data Creazione" FontFamily="Century Gothic" FontSize="15" BorderThickness="2"/>

but is seems that it has no effect (probably I'm not doing in the correct way).
Thank you, regards.

Roberto
