I want to be able to move an img around within its container once the image is zoomed in, because as you can see once you click the image it bees too big and you can't see the whole image. Also how can I make the image goes back to normal once it's not being hovered? thanks in advance.

// Zoom in/out clothing img
  $('.image').click(function() {
    $(this).toggleClass('normal-zoom zoom-in');
  });

.container {
  width: 800px;
  margin: 0 auto;
  border: 2px solid black;
  display: flex;
}

.img-wrapper {
  margin: 10px;
  overflow: hidden;
}

.image {
  width: 100%;
  height: 100%;
}

.text {
  width: 40%;
  padding: 20px;
}

.normal-zoom {
  transform: scale(1);
  cursor: zoom-in;
  transition: all 250ms;
}

.zoom-in {
  transform: scale(1.6);
  cursor: zoom-out;
  transition: all 250ms;
}

<script src=".1.1/jquery.min.js"></script>
<div class="container">
  <div class="img-wrapper">
    <img src=".jpg?format=750w" class="image normal-zoom">

Since you're using transform: scale() for the zoom effect it's faster and more correct to modify transform-origin to change the center point of the zoom effect on mousemove:

// Zoom in/out clothing img
$('.image').click(function() {
  $(this).toggleClass('normal-zoom zoom-in');
});

$('.image').on('mousemove', function(event) {
  // This gives you the position of the image on the page
  var bbox = event.target.getBoundingClientRect();

  // Then we measure how far into the image the mouse is in both x and y directions
  var mouseX = event.clientX - bbox.left;
  var mouseY = event.clientY - bbox.top;

  // Then work out how far through the image as a percentage the mouse is
  var xPercent = (mouseX / bbox.width) * 100;
  var yPercent = (mouseY / bbox.height) * 100;

  // Then we change the `transform-origin` css property on the image to center the zoom effect on the mouse position
  //event.target.style.transformOrigin = xPercent + '% ' + yPercent + '%';
  // It's a bit clearer in jQuery:
  $(this).css('transform-origin', (xPercent+'% ' + yPercent+ '%') );
  // We add the '%' units to make sure the string looks exactly like the css declaration it bees.

});

// If you want it to automatically trigger on hover
$('.image').on('mouseenter', function() {
  $(this).addClass('zoom-in');
  $(this).removeClass('normal-zoom');
});

// and stop when not hovering
$('.image').on('mouseleave', function() {
  $(this).addClass('normal-zoom');
  $(this).removeClass('zoom-in');
});

.container {
  width: 800px;
  margin: 0 auto;
  border: 2px solid black;
  display: flex;
}

.img-wrapper {
  margin: 10px;
  overflow: hidden;
}

.image {
  width: 100%;
  height: 100%;
}

.text {
  width: 40%;
  padding: 20px;
}

.normal-zoom {
  transform: scale(1);
  cursor: zoom-in;
  transition: transform 250ms;
}

.zoom-in {
  transform: scale(1.6);
  cursor: zoom-out;
  transition: transform 250ms;
}

You can use the mousemove event listener on the image with class .zoom-in to change the left and top CSS params. Make sure to set position:relative; on the image.

Example:

$(document).on('mousemove', '.zoom-in', function( event ) {
  $(".text").text(event.pageX + ", " + event.pageY);
  var positionLeft = event.pageX - $(this).width()/2;
  var positionTop = event.pageY - $(this).height()/2;
        $(this).css({'left': positionLeft, 'top': positionTop});
});

Here is a fiddle.
