If you're a petite woman in search of maternity clothes, you may be surprised to learn that the only maternity clothes especially sized for petites are maternity pants and jeans. As for tops, dresses, and other garments, it's a choice between petite clothing that is not intended to be maternity clothing and maternity clothing that is not sized for petites. The only other option would be to make your own maternity clothing or have it custom made for you.
The major sources for maternity clothes don't seem to find it worthwhile to cater to short women. Could this gap in availability be a business opportunity for some enterprising designer?
