Textured and lined geometric neutral dress

I LOVE this dress however I bought this probably 5 years ago and now it won’t fit me. I tried it on today to finally wear to an event and it’s a top tight around my stomach. I’m usually a size 2 or 4 so don’t let this size 6 throw you off. There is a small scratch on the gray part as seen in last picture. Otherwise brand new and this has never been worn except to try on.
