Hi,
this behavior come from some hikashop strange style (at line 19 in file media/com_hikashop/css/frontend_default.css you will see that for each invalid element it apply 5px to all borders)

Anyway to solve add this CSS code:

.control-label label.invalid{border:none;}

.controls input.invalid{border-width: 1px;}
