Shoes, Bags and Fit Notes
Shoe fit information
Shoe comfort depends on more than the size number: products in the same size can feel different because of their design and construction. Check each product page for fit notes such as pointed toe, round toe, standard or wide fit. For pointed shoes and closed-toe heels, choose the larger size if you are between sizes.
Bag measurements
Bags don’t need a wearable size, but DIID product pages show their dimensions as Width × Height × Depth. Handle drop is the distance from the top of the bag to the highest inside point of the handle; strap drop is the vertical distance to the highest point of the shoulder or crossbody strap when hanging.
One-size products
One Size doesn’t mean a product fits every shape or measurement. The product page gives the relevant measurements, stretch information and recommended fit range.
Understanding DIID fit descriptions
- Fitted – designed to sit closely against the body.
- Regular fit – a balanced shape that is neither tight nor oversized.
- Relaxed fit – additional room for comfort and movement.
- Oversized fit – an intentionally wider or longer silhouette.
- Cropped fit – a shorter body or leg length.
If you are between two sizes
- Choose the smaller size for a closer fit.
- Choose the larger size for a more relaxed fit.
- Choose the larger size for non-stretch fabrics.
- Use your hip measurement for fitted bottoms.
- Use your bust measurement for fitted tops and dresses.
- Use the longer foot measurement when choosing shoes.
