I've been to see the gorgeous Christmas windows at Harrods in London twice now. The detail is spectacular and they are true fairytale! The Little Mermaid window features a dress by Marchesa and below i've found some bits and pieces for the grown woman to get her own mermaid princess inspiration! First up this dress by coast is utterly divine, it features a fishtail skirt and a cinched in waist to flatter, £220 from Coast find it here. The message in a bottle necklace is from the Disney Couture Collection and was inspired by the little Mermaid, it is so detailed and so charming, £55 find it here. Finally these shoes would give the elegant dress a fun twist and feature a shell design in silver and gold, they are from my favourite shoe brand irregular choice, find them here for £79.99.
