Best way to put a border around ListView items - xaml

Question

I have a ListView and I want to put a border around each item in the ListView. Microsoft doesn't seem to have a system theme for the Border element.
What is the recommended way to theme the border so it looks good on Dark and Light theme?
Here is my ListView
<ListView ItemsSource="{Binding Products}" Header="My Header" Margin="10,5,10,5">
<ListView.HeaderTemplate>
<DataTemplate>
<TextBlock Text="My Header" Style="{ThemeResource HeaderTextBlockStyle}" />
</DataTemplate>
</ListView.HeaderTemplate>
<ListView.ItemTemplate>
<DataTemplate>
<Border>
<StackPanel>
<TextBlock Text="{Binding Name}"
Style="{StaticResource TitleTextBlockStyle}" />
<TextBlock Text="TextBlock 1:"
Style="{StaticResource ControlHeaderTextBlockStyle}" />
<TextBox Text="{Binding TextBlock1}"/>
<TextBlock Text=" TextBlock 2:"
Style="{ThemeResource ControlHeaderTextBlockStyle}"/>
<TextBox Text="{Binding TextBlock2}"/>
</StackPanel>
</Border>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
**************Edit 1****************
I should have put this. I want it in a Universal App targeted at WP8.1 and Windows 8.1, not just phone.

Answer 1

You probably just want the standard foreground color, right? (dark for light, light for dark). That would be the PhoneContrastForegroundBrush.
<Border BorderThickness="1" BorderBrush="{StaticResource PhoneContrastForegroundBrush}">

Answer 2

The previous answers lead me to look at system brushes and I found ApplicationForegroundThemeBrush, which I believe will work.
