This is an absolutely brilliant toweling dress that comes in blue or white (I have it in blue). It zips all up the front and has a draw-string and a hood and short sleeves.
It’s perfect for putting on after a swim/on the beach. (I’d always envied children their toweling cover ups.) Because I am not tall, the style fits me really well (I didn’t want anything too short) and comes to a few inches above my knees. I’m a size 14 and the L fitted me with room to spare. I swim every day and put this on after my shower and when I can’t be bothered to get dressed back into proper clothes, but don’t want to lounge around in a dressing gown, either. I love it, and am resisting the urge to buy two in case anything happens to the first one. But be warned: doing this (buying two of the same thing) will immediately render the first less special.
Pane Amore e Cha Cha Cha 
…I recall a friend we both know who used to walk back from the swimming pool with the towel still on her head. (I am a real buy two person, and can’t enjoy my favourite things, unless I have a spare in reserve, if possible).
Ooh I wonder who that was? I know what you mean about having one in reserve, but whenever I’ve done it, it’s killed the specialness of the first one for me.
