Shiori is a very delicate girl, so it's best to always remain gentle with her. This is a plus since she's easily taken by force without great risk in hurting her, but it's better to be safe and approach her casually just in case something goes wrong. When it comes time to tie her, no matter her outfit, the focus should definitely be on her legs and thighhighs since her inner thighs and hips are her best weak spots. Give her a gag that emphasizes her eyes. If everything went well with her first captivity, she won't mind being nabbed again later. One way to really make her happy is to feed her some ice cream at some point too.
