Speaking about the event , Millie 's good friend Laura Whitmore added : 'This will be my third year attending the Investec Derby and the fashion is just as much of a spectacle as the racing which is one of the reasons I love it ' Millie certainly knows a thing or two about how to dress for glamorous events . The star recently unveiled her spring/summer 15 drop full of bold floral patterns , hippy chic maxi dresses and the kind of festival fashion staples that she 's made her signature . 'When it comes to summer dressing , you 've just got to have fun with it . My clothes are really accessible and you can dress them up or down depending on the occasion , ' she told FEMAIL . As well as style expertise , Millie , who trained as a make-up artist before finding fame , is a beauty buff with her own eyelash range . BBC athletics presenter champion Denise Lewis OBE , left , and DJ Laura Whitmore , right , also star in the stylish and summery shoot for the racing event . Sharing her top beauty tips for flawless summer skin , the star - a self-confessed sun worshiper - says SPF is essential . ' I loved sunbathing all my life and now I am so worried about sun damage so I always wear a tinted moisturiser with an SPF in and some cream bronzer and pastel eyeshadow for a natural sunkissed look . ' Aside from fashion and beauty , fitness is one of Millie 's passions and she 's a walking advert for the healthy lifestyle she preaches . Whilst she 's confident enough posting videos of her squatting , boxing and participating in the oh-so-fashionable but gruelling SBC class , there 's one class Millie is afraid of trying . ' I really want to try this music video dance class at Frame studios but I am too embarrassed . I think it would be really fun and I probably need to learn to just let go of my inhibitions ! ' . As well as cramming in fashion design and fitness classes , Millie is preparing to release her debut book at the end of the month . If that was n't enough , she 's hoping to expand her eyelash range next year , is already working on her autumn/winter 15 collection and has some exciting health and fitness projects in the pipeline . Millie , left , and Laura both attended the Urban Decay VIP Spring Beauty Dinner at the Groucho Club on Thursday night in central London .
