Any man with an ounce of active brain matter knows that he should not answer every woman’s trick question: does my butt look big in this dress?

The makers of Wonderbum dresses have responded to a survey of 18,000 women, 85 percent of them unhappy with their bottoms.

There is no good answer to this suicide mission question.

If a man says “well, honey, perhaps … ” there will be a wall of silence in bed for weeks. Three years later, the nicest guy may still be hearing the words “you told me I have a fat butt.”

If a man says “honey, your butt looks great”, he will be accused of lying and his butt-loathing babe will be mad at him anyway.

The best strategy about answering that big-butt question lies in an emergency need to pee.

Dr David Holmes, an expert in derrieres, has found that modern diets and lifestyle, including exercise and lack of it, have transformed women’s butts into juicy fruits and one starchy vegetable. Teaming up with British retailer ASDA, Dr Holmes has developed a collection of Wonderbum dresses that celebrate every shape to its maximum beauty.
