Topshop is ramping up its lingerie offer at its flagship store on London's Oxford Street, with four brands set to debut in store by May.
Australian label Bulb will unveil a lower-priced collection, designed specifically for Topshop, at the end of May.
Prices for the range start at £20 for briefs and £30 for bras.
The Arcadia-owned retailer is also in talks with Patrick & Skinner, a new lingerie brand that launched at the end of last year, to design a less expensive collection for the chain.
Topshop unveiled a new range by Jane de Lacy this week, and last weekend it launched Laura Brooks for Topshop, which comprises five styles. Prices range from £20 for briefs to £45 for bras. Each style has its own name: Millie, Molly, Polly, Florence and Ooh La La.
Topshop said its branded lingerie area had grown considerably in terms of offer and space since launching 18 months ago.
It added that there was potential to take elements of the offer into other stores, although it said there are no immediate plans to roll out the concept.
