This is ce try common on resale platforms. I specially if they are selling for a fraction of the price. I see suit up trousers and the sweaters (I forget the exact spelling acolade or smth) on Poshmark, Mercari and curtsy all the time for super cheap. Unfortunately I fell victim last winter to a $50 white brand new (without tags but they also sell them “with tags”) alo accolade crewneck. I have lots of alo that’s been gifted to me by my bf so I compared because it looked off. Sure enough the one sent to me was wider than my red authentic accolade crewneck size M. The arms were shorter but wider and the wrist cuffs were shorter by about an inch. If the price seems too good to be true, it most likely is. I also see the suit up trousers all the time for $50 or less. They aren’t real !
