Can anyone suggest a top to go with this skirt?

I really like the blue top it's been paired with in the photo - but I definitely need longer sleeves and to be able to wear a bra with straps. In a size 18.

Anyone seen anything that might do the job?

I think you just need something very simple that's bang on for colour. I'd buy the skirt and then take it to a big department store/mall to find something in exactly the right shade.

Helena top from Hobbs?

Several blues but not all sizes left and you might not want jersey

Did you buy in store or online? I tried some coast skirts recently & found the sizing very inconsistent...

I would go for a simple navy top like they have in one of the pics. Alternatively, I don't like the style of the silver top they've shown, but the colour goes surprisingly well.
