Sometimes a removable Liquidation sticker is applied
Sometimes the piece is missing the paper store tag
Sometimes the piece was part of a set and some, or the rest, of the set is missing. The remaining piece(s) are still sellable.
Sometimes packaging may be imperfect in some way; dented, ripped, stained, etc
On very rare occasion there is a rip along a seam or under an armpit that we didn't see. Again, these are usually very simple repairs with basic sewing knowledge. We try to remove all major damage that we see.
It is not possible for us to catch every imperfection. We sort over 10,000 items a week so we do not have time to analyze each piece. You should expect there could be imperfections we did not see.
