bikini help

[MistySkiesAreGone]

I've been looking endlessly at bikinis and have ordered a few but no success. I think I've whittled down what I am looking for:

Bikini bottoms must be roll top, as the roll suits me (pear shape) but high also looks stylish
Either printed or not - navy, black, bright floral etc., but nothing too crazy
Ideally a soft halter neck design like this one - this is great but the bottoms are not roll top:

Also this:

I need a size 14 bottom and a 12 top, but everything is out of stock - I find a top, I can't find the bottoms etc.

Budget £80. Tried Next, M&S, JL. Any suggestions?

Sports Direct?

I bought a load from there last year at sale prices

Mint velvet seem to have quite a few separates that include mix and match options with both the roll top and the halter.

Bravissimo?

My bikini top is Freya and I have 3 pairs of plain black bottoms, separates work best for me

thank you so much everyone. @Procrastatron I've ordered that thank you. I think I saw it ages ago but dismissed the colour. but actually it's exactly what I want and the colour is pretty inoffensive : ) It also has a high neck top which I have also ordered as these are flattering on pears and it looks handy for swimming.

I've also ordered this one in a larger size as they come up small:

I have a Sports Direct and also Decathlon in the local town so failing these will look there. I did look at this in Bravissimo but I don't think the straps aren't thick enough - I have a lot of shoulder width that needs to be broken up: www.bravissimo.com/products/the-hills-bikini-top-ms148/#purple-print-ms148ppr

Oh I see there are more halter necks in the sales at Bravissimo...still not quite right though.

More suggestions of places like Bravissimo that specialise in boobs are good though!

I have just bought a few bits from Pour Moi, a mix of tops and bottoms as they do them as separates. The tops are also in bra sizing rather than clothing sizing which I found really helpful
