Next year I'm going abroad for a 'special' holiday and I'd like to replace my current swimwear which I've had for years. I'd love nice bikinis and coverups, but tend to have a cider budget for my champagne tastes 
Where is good (online) to find nice swimwear and coverups etc, and would I be better to wait until it's the depths of winter here or is there a 'good' time to buy?
