Sure! Unless you spend a fortune on unique designer pieces, how many pieces of new clothing can you expect to keep their value? If the item is cared for by the new owner, it can be re-used or re-sold once again.
Although not every vintage garment is sought-after, there is a collectible market for vintage clothing. Many pieces accrue value with time. Because of these reasons, wearing vintage clothing is always a win-win situation.
Buying vintage is money well spent.
