The listed prices in this edit range from £37.50 to £59.00. Value also depends on fit, fabric care, delivery cost and expected repeat wear. A slightly higher-priced piece may be the better purchase when it works across several occasions.
Before you order
- Check the retailer size guide before ordering.
- Compare delivery timing as well as the listed product price.
- Choose items that can work with clothing and footwear you already own.
Always check the size chart, return window and delivery estimate. For a time-sensitive event, do not rely on a product remaining available later.
