    What a relief!

    Getting my saggy old self into a swimsuit that made me feel wonderful was just a joy. Fits perfectly, tucks me in where it should, and gave me all the confidence I needed to get back into the sea. PS the sizing advice was spot on PPS thanks to Sarah W for putting me on to this. Nothing like word of mouth from a person you admire
