A data-backed edit of 10 formal options from 3 UK retailers, with listed prices from £15.00 to £37.50.
This Trend Sift edit uses the live catalogue to organise a manageable shortlist. It does not claim that every product is identical or that one retailer will always offer the lowest final cost.
The products below come from 3 retailers: Chi Chi London, Hobbs UK, Phase Eight UK. Prices, sizes, stock and delivery can change after publication, so the retailer page remains the final source of truth.

The listed prices in this edit range from £15.00 to £37.50. 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.
