DD (9mo) has a huge cloth bum, I tend to put her in leggings or tights, or tracksuit bottoms. Am trying to buy some clothes off ebay but without knowing what brands have larger waistbands its a bit difficult. I know that Next are no good as the waistbands are always too tight and the rise too low, even in a size up. Any suggestions that I could look out for? I don't want to spend a fortune.
