Another reason that I'm not particularly fond of maternity shops and maternity advertisements: they often feature women in excessively high heels in their advertisements [case in point: see this recent advertisement on A Pea in the Pod's website - a woman in a short dress with very high heels].
During my pregnancy, some people warned me that wearing heels during pregnancy was unhealthy. So I did a few quick Google searches on the Internet and found this and this. Apparently, there's no specific concensus on the issue, but most experts agree that lower heels (1/2 to 2 inches) are better.
In fact, the American Podiatric Medical Association (APMA) agrees that high heels -- which they define as pumps with heels of more than two inches -- are not the best footwear choice for anyone."
So, why-oh-why, do maternity advertisements always feature women in 3-4 inch heels?
