Annoyingly, I can only find them on Amazon US and they're out of stock, but here they are!http://www.amazon.co.uk/JERZEES-NuBlend-Sweatpants-True-Red/dp/B004Y1CYBE/ref=sr_1_15?ie=UTF8&qid=1334440597&sr=8-15
Ok, these aren't the exact same sweats Bella wears but they're almost the same. Buy them in 'Maroon'!http://store.americanapparel.co.uk/2102.html?cid=199
Buy this in 'Heather Grey' and you'll have Bella's gym top, voila!And finally, here's Bella's 'Goody Stay Put Grip Headband' (which she wears CONSTANTLY throughout all films. Sorry, I can only find it on ebay, so you'll probably have to look for it yourself but if you're lucky enough to catch these two lots, here's your headbands!

Off to prom~
The dress: http://www.amazon.co.uk/Blue-Banana-Cobalt-Halter-Dress/dp/B002KM9B5Q/ref=sr_1_9?ie=UTF8&qid=1334492041&sr=8-9
Amazon, Bella prom dress look-a-likey. It's not the exact one, but it works for me!
Cardi: ebay - I can't seem to find a replica, so I recommend just buying an off-white cardi, some beads and flowers and get creative!
Shoes: Converse! (and one of those cast things)
Yet again, the turquoise cuff! LOVE IT.
I still recommend this one, but you can buy the NECA one if you want c: This one is more like Bella's I think.Will you marry me?
Here's our lovely couple! >:)
Perfect replica!
Bella's Wedding shoes, VERY EXPENSIVE! :o $1295.00, apparently £817 :O (£816.931617)
That, my friend, is a rip off. It's more expensive than the wedding dress!
But they're beautiful
American again, sorry! But it's only £14 so grab it while it's on sale c:
Wedding and Engagement rings - NECA on Amazon
VOILA!
She wears these a couple of times in the films, one in the baseball scene when Bella and the Cullen's first meet James, Victoria and Laurent.
Bella's bag everyone knows and loves. It's really hard to find, but amazon have it! I don't think I need a picture of Bella with it!!
Oh, I love these, however I have to admit I didn't have the money for them so I bought some £3 navy primark ones and stitched the white stitching on!! >:)
Here it is, the NECA one. They got it right this time.
This is the dreamcatcher Jacob gave Bella in New Moon. I made mine myself buy buying the separate stuff, but I've found a bid one off ebay, but it's REALLY expensive.(
Here it is on amazon, but I bought mine from ebay for £3 so I recommend you just search 'Bella wolf and heart bracelet' in ebay and you'll get one.
