# The amount a garment can be taken in or let out

Actual limits depend on seam allowance, fabric type, and garment construction, but the table below gives a practical rule-of-thumb.

| **Garment** | **Typical ****Take-In****Limit** | **Typical ****Let-Out**** Limit*** | **Notes** |
| --- | --- | --- | --- |
| **Trousers / Jeans** | Up to **5 cm** (2 in) at waist & seat | Up to **3 cm** (1¼ in) if extra seam allowance exists | Many jeans have only 1 cm each side—let-out often impossible. |
| **Skirts / Dresses (unlined)** | 1 size down (≈ 4 cm at hip) | 1 – 1½ cm per side seam | Seam allowance hidden in overlock; check first. |
| **Skirts / Dresses (lined)** | Same as above + lining adjust | Let-out limited to lining width | Lining usually tighter than outer shell. |
| **Suit Jackets / Blazers** | Up to **4 cm** total at waist | **2 – 3 cm** at centre-back | Shoulder width cannot be changed without a recut. |
| **Shirts / Blouses** | **5 cm** total via side seams or darts | Rarely more than **2 cm** | Fabric prints may misalign after large let-out. |
| **Coats** | 1 size down (body & sleeve) | Usually **0–2 cm**—fabric often fully trimmed | Heavy wool hides new seam lines well; leather does not. |

*Let-out always depends on spare fabric inside the seams.

### **Quick checks before ordering**

1. **Pin & try on** — If the garment wrinkles or pulls after a 4 cm pin, more may distort the shape.
2. **Feel inside seams** — A wide overlocked edge = room to let out; a narrow stitched edge = little or none.
3. **Consider recut** — More than one size change often needs a full recut, quoted separately.

### **Tailor confirmation**

When you place the order:

- **Add exact numbers** in *Alteration Details* (“Take waist in 3 cm”).
- Upload clear photos of seams.
- The tailor will accept only if the change is feasible; otherwise Support will advise before you ship.

Use these limits as a guide—every garment is different, and tailors will always confirm what’s realistically possible.
