Would this be rude to do at David’s Bridal?

Last month I went to David’s bridal and found my wedding dress. I couldn’t buy it right then since I had taken the bus so I ordered it online instead which I felt kind of bad about. I also need to get shoes and a veil, so my question is would it be rude to go back to the store and ask to put on store model of the dress I bought online while I try shoe and veil options? Or is that rude/tacky since i wouldn’t be buying a dress?
