Formal lace dress

I’m not sure what brand as all tags are removed. As a result I also am not sure about original price, but selling for what I think it is worth. There are also no size tags on it but I am a size 0-2 and this fits slightly wide. My best guess is it is a 4. It is in great condition and has only been worn once. It is a very pale blue with a sheer back and pretty lace detailing.
