The law requires that any item of clothing (including a pair of shoes) must be:
When you buy an item of clothing that is faulty before it has been used, you should be entitled to a full or partial refund. This won't be the case, however, if you had a reasonable opportunity to examine the item when buying it and the fault was so obvious that you should have noticed it.
Whether you're entitled to a full refund depends on whether you've 'accepted' the item of clothing. The Sale of Goods Act states that you have a 'reasonable time' to examine goods after purchase before they're regarded as being 'accepted' by you. It doesn't specifically state how long a 'reasonable time' is; it depends on factors like how often you use the item, the type of fault (whether it's obvious or not) and whether you've continued to use the item despite knowing it has a fault.
If you've accepted the item of clothing, you may be entitled to a repair or replacement. The seller is entitled to refuse either of these if the cost of doing so would be excessive in comparison to the alternative. Whatever remedy is agreed, it shouldn't result in undue inconvenience to you.
If you only worn it a few times before a fault arose, you may be entitled to a refund (assuming that you didn't have a reasonable opportunity to examine the item when buying it and the fault wasn't so obvious that you should have noticed it). However, you'll only be entitled to a refund if you haven't accepted the item (see above).
Alternatively, you may request that the item be repaired or replaced. If the fault is only minor and can easily be put right, it's reasonable to accept a repair. This repair should be done to a satisfactory standard at no additional cost to you. If the repair isn't carried out to a satisfactory standard, you're entitled to request a refund.
In the first 6 months from the date of purchase, when you return an item of clothing to request a repair or replacement, you don't have to prove that the item was faulty at the time of sale. There's an assumption that the item of clothing was faulty unless the seller can prove otherwise. If you opt for a refund rather than a repair or replacement, the onus will be on you to prove that the item was faulty at the time of sale.
If you've worn it more than a few times or had a reasonable opportunity to check it, you might not qualify for a refund, but you may still be entitled to a repair or replacement.
A repair should be carried out within a reasonable period of time and without causing you significant inconvenience. Any repair should restore goods to a satisfactory condition. If it's not restored to a satisfactory condition, you should be entitled to a partial refund. (This will be less than the price you paid to allow for the use you've had from the item.)
If the item of clothing can't be replaced or repaired economically, you're entitled to a refund. The seller may make a reduction from the price you paid to allow for the use you've had from the clothing.
If anything else has been damaged (e.g. if the colour ran due to a fault and discoloured other clothes), or you're out of pocket in any other way, you may be entitled to compensation over and above the price of the item.
You have no rights if:
Remember that no items last forever and all clothes need to be looked after to avoid unnecessary damage. However, if there are genuine problems with an item of clothing, the seller must fix the situation. The seller can't tell you to go back to the manufacturer.
As soon as you've determined that there is a problem with an item of clothing that you've bought:
