The tag alias #81950 bra_outline -> bra_lines is pending approval.
Reason: I accidentally submitted this request as an implication originally.
From incorrectly submitted request description:
I believe both tags are representing the same thing, though bra_lines already has an established description. Also might be worth noting that it using bra_lines would be consistent with panty_lines whereas "outline" is used more for anatomical details such as anus_outline or nipple_outline.
