# When a Garment Is Unsuitable for Alteration

Most clothing can be altered, but some pieces simply can’t be adjusted safely or to a quality standard. Orders that fall into any category below will be declined or cancelled.

| **Issue** | **Why We Can’t Alter It** |
| --- | --- |
| **No seam allowance** (edges trimmed to 0 cm) | Nothing to let out; fabric may fray if re-stitched. |
| **Extreme size change requested** (> 2 sizes up or down) | Pattern lines distort; fit and balance can’t be preserved. |
| **Glue-fused hems or bonded seams** | Heat destroys glue; stitching leaves visible marks. |
| **Heavy beadwork / sequins along seam** | Removing embellishment adds hours and risks damage; tailor may suggest a full rebuild instead. |
| **Severely sun-rotted or brittle fabric** | Needle holes enlarge; fabric can tear during sewing. |
| **Water or smoke damage** | Stains and odours set; pressing may worsen marks. |
| **Synthetic PU leather delaminating** | Material flakes when folded, making hems or seams impossible. |

### **What happens if I submit one of these items?**

- Tailor marks **Job Failed (Customer Issue) – Returned**.
- Item ships back to you; **10 % admin fee + return postage** is deducted from the refund.
