There's only one in trades, no price, anyone knows how much would it go for? Thanks! :)
I did a bit of research and the last one sold on the forums went for around 270k (somewhere around March). I also found other threads - a lot of old ones at that - where the dress sold for 50k-200k, sooo... yeah. Apparently it used to be a cheapie, but since there's none in SS anymore... well, it's up to you to give it a 'new' price unless you want to wait until another user puts their dress in SS (how long that may take knows no one). Oh, and I checked subetalodge as well. They're usually legit with the estimated user shop price and it says 276k, so that's almost the same price it went for in March. Could be that the last one in SS was priced that way until it got bought up.
Well, hope that helps a bit in deciding to price it on your own maybe. c:

Oh, my, so much info, thank you heaps! ❤
Ladies, it is overated because it was Canada Day recently (July 1st), that's why everyone bought it up. Otherwise yes it used to be pretty cheap (I got mine for pretty nothing).
Well, "edit". I misread, but what I wanted to say : I usually buy up things and then price them at 51015m. Never try to price it too high like 50m. No one will ever spend that much on a worthless item, however 10m is still an amount of sP some people could be willing to spend. :)
Well, thanks for the update :)
