Size 18 'trendy' hoodie?

[bumpypaws]

I'm looking for a hoodie for my sister for Christmas - she asked for a Superdry one (she's into labels is DSis!), but they don't go big enough for her. She's a size 18, and I've been trawling websites to find one in that size, but not much luck!
I've found some on North Face, but would like more options - any ideas?

ooh i just got one from h and m, it's really nice quality

Fat face go up to size 18 and do loads of hoodies. Joules do, but not sure about how trendy or if they have hoods tbh. I bought a japanese anime type one for my sister last xmas, she's an 18/20 so will check where it's from as I just went where she told me!
Best bet might be to try House of Fraser/John Lewis as you can narrow by size & they do lots of brands.

Thanks all, will have a look at your suggestions!

Pineapple?
Nike?

I quite like superdry too but no way was it going to fit me, i settled with a fat face hoodie and already i've worn it quite a bit so a good buy, has washed well too.
