The afternoon of the Royal Wedding Day saw fake tan flying off the shelves with sales up 219 per cent compared to the same day last year. The following day was almost as successful as shoppers, inspired by the wedding highlights on TV, boosted sales by 200 per cent.
Rumours are abound as to how the Middletons achieved their sun-kissed looks, from Kate's natural glow to Pippa's golden tone, with professionally applied artificial self tan thought to be the most likely solution.
Sara Stern, beauty director at Debenhams said: "You simply can't underestimate the impact that Kate and Pippa will have on the beauty industry.
"Already streams of wannabe princesses have been flooding into our stores looking to achieve their healthy, groomed look.
"In particular, Kate's more subtle shade of tan is perfect for big occasions like weddings. A light tan to complement your skin tone is more appropriate than the deeper, more noticeable shades used on a night out".
Debenhams' in-store tanning experts have been inundated with phone calls and in store queries about tan-etiquette - how to look your very best at a wedding without over-shadowing the bride or scaring off the best man.
Stern advised: "Skin prep is vital to avoiding those tell-tale tide marks. Exfoliate and moisturise well in advance and apply slowly and steadily. Choose a shade that is not too distant from your skintone and use different products for face and body.
"Take inspiration from the new Duchess of Cambridge and embrace bronzing powder and highlighters to create definition and enhancement - a look that will dazzle from Westminster Abbey to Gretna Green".
