Help me find a swimming costume!

[LadySybilPussPolham]

I'm 5'7, size 10/12, VERY small of boob and have a longer than average torso. I don't think I've ever found a properly fitting swimsuit.
My latest purchase (and return) was Zoggs swimwear which looked nice but was too short and too big in the chest.
Can anyone help? Budget £40ish, ideally I'd like some padding/shape in the bust and it needs to be suitable for actual swimming!
TIA

Boden has a Boyleg swimsuit which might fit the bill. I have a similar model from previous years and it's great. There must be a discount code around.

Long Tall Sally? I'm 6ft and have a speedo from there.

Thanks all, will have a look at Boden. I must admit I'd ruled out Long Tall Sally because a lot of reviewers said costumes were no longer than standard ones. I don't really want a tankini as they ride up and I also have a large scar on my stomach
