In 2015, an estimated 16bn jellybeans will be eaten worldwide. And why not?!

From chocolate, to blueberry, to popcorn; everyone has their favourite flavour of jellybean.

This Wednesday (April 22) has been dubbed National Jellybean Day, and what better way to celebrate than by eating them until you feel giddy with sugar?

If jellybeans aren't your forté, you can always celebrate the sugary-sweet day with cola bottles, sherbet or licorice... When it comes to vintage sweets, do you really need an excuse?

Here are the best sweet shops in west London to get your hands on some jellybeans to celebrate:

Charlie's Sweet Emporium

Like Willy Wonka's come to life! This traditional old English sweet shop has glass jars filled with handmade retro treats. Adults and children alike will love coming to sample these cute sweets.

21a Buckingham Palace Road, Westminster, SW1W 0PP - 020 3632 2436

Sweet Memories

This teeny sweet shop is reminiscent of little Harry Potter shops, and is brimming with retro and modern sweets (my favourites are the popping candy sachets!) Sweet Memories also sells ice cream and chocolate if traditional sweeties aren't your thing.

Also has a working train-track ride in the window to spark your childish delight!

Mrs Kibble's Olde Sweet Shoppe

This sweet shop specialises in traditional treats and personalised gifts, such as "mix your own jar" sweets. A firm favourite for old-fashioned sweet lovers.

Try the Seriously Sour drops if you dare!

Mr Simms Olde Sweet Shoppe

A growing franchise of Victorian-style sweetshops, Mr Simms is one to visit for a nostalgia hit!

A reviewer from an independent website said: "Stepping into this tiny shop was like a trip into a Harry Potter-like candy shop. I didn't understand everything I was looking at but I certainly wanted to try. It was like sugar took another form and was beckoning me with its siren song."

A Great British sweet shop bursting with old favourites and contemporary delights, including Chili & Cherry Licorice! The perfect hipster haunt and brilliant for gifts.

A reviewer from an independent website said: "I don't think this candy store could be cuter if it tried. It's candy-covered awesome. A stroll back to candy stores of yesteryear. Bright colors, outstanding variety, and just a whole lot of fun. I wanted to buy one of everything."
