Answer:
hyperlinks
Explanation:
Javier should use hyperlinks to show the users the possible choices for their clothing.  This is really a terrible question and not likely in any real world scenario.  Fashion is always forward thinking and on the cutting edge.  When was the last time you went to a fashion website and were left with only choices to click on a hyperlink?  As Tim Gun would say "Make it work."  If I were able I would include a hyperlink using the previous sentence as the clickable link with a URL reference to 
https : //en.wikipedia.org/wiki/Tim_Gunn (spaces after https to make this link not get censored)
to illustrate the way to show that hyperlinks have no real application on modern fashion website.  But they would have great utility here inside the answers section.  But they also are cause for a securtity concern and may be killed by the moderators

Like that when you arrive to the fair you can go directly to them and find them easily which will save you a lot of time as you won't be walking around the whole place to find them.
