BnS Fashion's character galleries are a chance for people to show off their characters. This is not intended to be a preset sharing site, but people can choose to include one if they want. If there isn't a preset link on a character post, the submitter did not include one. Don't bother to ask me for the link (here or on social media), I don't have one. Repeatedly asking for one in the comments or saying "where's the preset link?" is unlikely to convince the submitter to provide one. Adding your email address to the comments is an excellent way to ensure you receive a ton of spam email.
