It happens every season. We will tell you before you reorder and offer the closest match, with a sample if the difference matters. Colours are the usual casualty.
When a garment is discontinued mid-contract, ask about matching by spec rather than by name — a 'closest equivalent' from the same fabric weight and cut usually reads as identical once branded, even if the product code has changed. We keep a swap list for exactly this reason.
The questions are free. So is the quote.
