Rounding boxes in commerce & contact form

Site URL: http://www.peterotoole.ie/shop

I was wondering how I could round these boxes below for Size and Quantity in my Shop and also on my contact form similar to what I have done with the other buttons on my site such as the 'Add to Cart' button.

I was also wondering how I could align the whole section on the right with the top of the photo on the left in my shop. ie align the text 'Cork City Hall Rainbow' and the section underneath with the top of my photo?

Thanks a mill!

@Peterotoole Add the custom CSS code below. See article on how to do that: https://support.squarespace.com/hc/en-us/articles/206545567-Using-the-CSS-Editor 

CSS

/* Round corners on form fields  */
.ProductItem-details input, 
.ProductItem-details select,
.ProductItem-details textarea,
.form-wrapper input, 
.form-wrapper select, 
.form-wrapper textarea  {
  border-radius: 5px !important;
}


/* Override top alignment of product details  */
@media screen and (min-width: 768px){
  .tweak-product-basic-item-content-alignment-top .ProductItem-details {
    padding-top: 0px;
  }
}
