He's been making pants! And what jolly pants they are too. We like this fun apple green polka dot set with pink lace trim From bjornborg.com Photograph: PR Bra, £18, and knickers, £10 The long line silhouette of this underwire-free blossom bra is super-cute but still holds your bust. The perfect spring set to wear under a silk blouse or show off the straps under a cashmere jumper. We adore ... By Asos Boudoir from asos.com Photograph: PR Bra, £17.50, and matching hipsters, £8.50 Sadie Frost and Jemima French certainly know how to design with a girlie touch, and their Floozie underwear line for Debenhams is no exception. This balcony bra with its feminine bow print edged in pink is simply divine Floozie by Frost French from debenhams.com Photograph: PR Bra, £8, and matching knickers, £5 We can't promise that this will survive too many washes, but we recommend handwashing all underwear anyway, to prolong its life. We love the look of this set, but you do get what you pay for From matalan.co.uk Photograph: PR Bra, £26, and matching shorts, £14 This superboost plunge bra is available in sizes 32A-38G. The plunge bra gives a great rounded shape and good support. The bold floral print edged in lace looks great under a sexy black dress.

Snap up this gorgeous set from Claire Henry's (Thierry Henry’s ex-wife) Dirty Pretty Things label From dirtyprettythings.uk.com Photograph: PR Jardin bra, £22, and briefs, £12 It would probably be treason if we ran an underwear gallery without mentioning M&S. There is good reason why they are the best-loved lingerie retailer in the UK: excellent quality for great prices. If you are size A-E, the choice is huge. We would, however, like to see them adding to their cup sizes with double E and F, but this is a minor gripe From marksandspencer.com Photograph: PR Nursing bra, £26, and shorts, £14 Midnight Grace's range is specially for larger cup sizes D-G. This style is a nursing bra and is among the prettiest we have seen (and we've seen a lot of frumpy white ones). The pants come in short and brief styles Midnight Grace by Figleaves from figleaves.com Photograph: PR
