Just because it's hidden under that new dress or those nice jeans doesn't mean underwear isn't affected by the latest trends in shape, colour or pop culture.
In fact, ready-to-wear trends directly influence bra shapes, especially necklines. So, after square necklines prevailed on the spring/summer runways, lingerie designers expect higher demand for balconnet bras with horizontal necklines, says Philippe Vertriest, design director for Marie Jo.
'Also, we see more tops and dresses with cut-outs in the back,' Vertriest says. 'In the Marie Jo collection, you see that reflected in a couple of bras with dramatic back design features.'
This season sees the return of blue - a ready-to-wear trend that started about three seasons ago. 'All shades of skin tones are new and very welcome in lingerie land,' Vertriest says. 'And we see a continuation of the purple and lilac trend, with hot pink as a newcomer.'
The 1950s and '80s have also made an impact on lingerie trends this season. The 1950s recall the 'Mad Men' look with narrow waistlines, round curves - often enhanced with shapewear - and an uplifted bust.
Triumph's new Sexy Cushion Maximiser has a push-up effect that looks natural and feels soft. The cups are made from technologically advanced memory foam, so they mould to fit individual body contours. The bra also comes in on-trend colours such as pink and blue.
