“Light blue graduation dress”

I’m disappointed in myself for not quadruple checking my order, because it was an expensive purchase for an elementary school dance. The name of the dress has the words “light blue.” I had been searching for a light blue dress all over the internet and when I came across this, I immediately knew this was her dress.
The selection was unfortunately already made since I chose dresses in stock. And I did not notice there were other options, since it’s normal for websites to post the same dress in numerous colors. I assumed I had landed on the light blue.
The dress is well made, but my daughter was sad to “feel like a bride” with the ivory color already selected.
At the end of the day it was my fault.
I emailed the company suggesting that they keep color specific named dresses, when the costumer has various dresses to choose from. The website seems to be constructed fine otherwise. But these are expensive dresses shipping outside of Canada. It is a hassle to return or exchange.
I have not heard back but I hope they take the suggestion.

Thank you so much for your thoughtful review

We truly appreciate you taking the time to share your experience and your kind words about the quality of the dress. At the same time, we’re very sorry to hear about the confusion regarding the color — we completely understand how important it is for your daughter to feel just right for her special event.

Your feedback is incredibly valuable to us, and we will certainly take your suggestion into consideration as we continue to improve our product listings and overall shopping experience.

Thank you again for your honesty and support
