I'm a 55 and overweight, size 22. I'm on holiday and it's boiling. I brought a bikini with me (full briefs and we'll fitting top with a bit of a frill to add extra cover) but only I tended to wear it in our private garden and change to go out to the communal pool. Yesterday it was so hot that I thought bugger it, I'm going in as I am!
Nobody ran from the pool and my family haven't disowned me. I don't think I would wear it at the beach at home with friends but I'm not going to see any of these people again!
