Sure I can try to help. Firstly i’d check the tag - this looks exactly like an Infanta dress. If it is Infanta, then i’d proceed to sell it. Most Infanta dresses are like 20-30 USD on their original taobao site, but with shipping costs to the USA they may be around 40-50 USD, which may be less likely to sell but it would be understandable! I would not go higher than 50 to be honest. If it were a design replica from a random brand, I personally would not even sell it on LM or I’d sell it for like 10 bucks to a friend/comm member. Replicas barely hold any resale value unfortunately which is why most lolitas discourage buying them. I hope this helps!

By the way, if you’re selling this cheap to a friend or comm member like I suggested, it is always important to disclose that it is a replica. Sometimes selling a replica without one’s knowledge can be a bannable offense in some groups.
