details about product: Button-Down Collar Non-Iron Oxford Multi Check Shirt - Dark Pink

I'm sorry to hear that this shirt didn't fit like the large size. I can see that this is the first time you've ordered a formal or business casual shirt with us. Whilst our large size equates to a 16-16.5 neck size, this shirt was ordered with a 17.5 neck therefore resulting in a much larger shirt that is required. I've included some sizing and return instructions below to get you started on the way to finding a perfectly fitting formal shirt. It certainly is disappointing when an item that you've so been looking forward to trying on just doesn't fit. Please note that not all retailers do not measure the same and some of our customers do not take fresh measurements and follow our unique sizing instructions before ordering. This is so very important to finding the right size from the get-go. I'd encourage you to check your measurements again via our "how to measure for a CT shirt" video and then consult the CT sizing guides on the website for your best fit before processing your online return or exchange.
