Have my eye on this Boden swimming costume but not sure what size to get:
www.boden.co.uk/en-gb/womens-swimwear/swimsuits/s0041/womens-talamanca-swimsuit
I'm usually a 10, occasionally a 12 on the bottom, 5ft 3.5in but with a long body. So not sure whether to get 10 or 12, or regular or long 
To save me having to order four, does anyone know if they come up large or small?
