I would recommend creating a redirect through .htaccess or your cpanel.
If you use a cpanel platform you can manage a redirect through this feature or if you have to redirect through manually made htaccess file
Code:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^bearsshop.co.uk$ [OR]
RewriteCond %{HTTP_HOST} ^www.bearsshop.co.uk$
RewriteRule ^/?$ "http\:\/\/www\.royalteesclothing\.co\.uk\/bearsshop\.co\.uk" [R=302,L]
This is an example only there are many ways you can run these.
You can place the above in a .htaccess file and see if it works. But it may not just give it a try see what happens. Place this file inside the root directory of bearsshop.co.uk ftp
