Consumers can choose the £9.95 fast delivery option at checkout on the brands’ websites, following a pilot scheme that has been running in London since May.
The retail group will now offer the service to those who live in and around Birmingham, Manchester, Leeds, Edinburgh, Glasgow, Liverpool, Bristol, Thurrock, Cardiff and Belfast.
The move comes as high-street retailers look to offer time-strapped and cash-conscious customers more varied ways of buying goods.
During the trial period, the retailer experimented with a promotion that offered the 90-minute delivery service for just 90p.
Plans for further marketing activity have not been finalised.
The delivery service is carried out in partnership with Shutl, an internet start-up that sources local same-day couriers.
Clothes are collected from stores and delivered direct to customers in order to avoid the need for a centralised warehouse.
Hash Ladha, group multi-channel director at Aurora Fashions, said: "Our customers want the freedom and flexibility to shop and buy in whatever way best suits their lifestyle.
"They can now order a product across any of our brands in the afternoon and be wearing it that same evening, which is a fashion first."
Rival group Asos offers same-day delivery in the M25 area for £7.95, if customers order before 10am.
