Long- line hoody?

[Onynx]

I've started to do a bit more walking- trying to get rid of the effects of the past year of lockdown/eating my feelings. I'm approx a size 14, 5ft 4" and I'm struggling to find a hoody long enough to properly cover my bum. Would any of you have any advise please?🙈

This just arrived - it's soft, fairly thin sweatshirt material, and the colour is lovely. I'm 5'4 and its definitely bum-covering.
