Why do you think petruchio makes an issue about kate's clothes

Petruchio also exercises his control over Kate by controlling what she wears later on in the play. Before the pair set off for Bianca's wedding in Act 4, Petruchio causes a big ruckus over the clothes and hat that have been custom made for Katherine. Petruchio claims they're not up to snuff and insists that he and Kate wear old rags to Bianca's wedding. Kate is livid – like a toddler, she's not even allowed to pick out her own clothes. She's also not allowed to complain about this because Petruchio tells her to zip it, or else they're not going to Padua. This certainly has to do withthe give and take of control that both Kate and Petruchio exercise throughout the play.
