Adele was torn between two outfits for her performance at Glastonbury festival.

The 28-year-old singer songwriter was toying between two Chloé dresses for the annual music extravaganza just 48 hours before gracing the Pyramid stage at the annual music extravaganza, which saw her headline on June 25.

Speaking about styling the power house for her 90 minute gig, the creative director of the luxury French fashion house, Clare Waight Keller, said: ''[I] fitted the dresses on her on the Thursday before. I was at her house and she was going between two looks, before deciding that [the one she wore] was 'more Glastonbury.'

''When she had the dresses on she twirled around asking us what we thought. She's so cool, such a big personality, I love her.''

And the creative mastermind has revealed the designer label's bohemian vibe is perfect for festivals, and was what Adele most wanted to channel in her black maxi embroidered dress at Glastonbury.

She explained to the ''There's always been that bohemia about Chloé which is so linked to festival culture, the idea of being a free spirit. You can be who you want to be for that weekend and do things that you wouldn't normally do.

''The history of festivals is about this very sense of spontaneity and sense of freedom. I think the fact that there have been so many English designers has [also] seeped in a bit to the culture [of the house]. There's a feeling that these long flow-y dresses which might be worn for evening dress for some people, can also be something you can fly around a festival in.''

Meanwhile, the mother of one - who has son Angelo with her partner Simon Konecki - has revealed playing at Glastonbury was ''the best moment of my life''.

Speaking previously, the 'Hello' hitmaker said: ''Oh my God, this is the best moment of my life. Glastonbury means the world to me, I'm not even lying.

''I have always wanted to do this but I've been too scared.''
