I bought a dress about 2 years ago for my upcoming wedding (was supposed to be n December) but because of COVID our venue and everything changed....along with it my love for my dress, and the fact that it doesn’t really match my venue

I’m trying to sell it on StillWhite, and have found a dress that is perfect on Etsy.
Has anyone had any experience with buying their dress on Etsy? The shop I’m considering is Wardobe by Dulcinea and they have great reviews. All the pictures that I have seen of their finished product (customer posted review pictures) look the same as what is shown on the website. They do no accept returns (which is what I’m finding at most places so this isn’t necessarily unique to this shop)
I’m also a little worried because I don’t want to have bought two dresses, possibly can’t sell the first or that the second one won’t be great! Ahh!
Any advice is appreciated!
