A pin up of Erza Scarlet
She wears a red black plaid shirt - unbuttoned. Under this shirt she wears a super tight black crop top - we can see her hard nipples poking through the top.
Give her a navel piercing.
As pants she wears super tight blue jeans - they are unbuttoned too and we get to see her red slip / thong she wears under her pants.
And to finish the outfit she wears red sneaker.
