Sales trends were obtained from market research conducted through the Internet. Four types of half top nursing bras were chosen for the research: crossover style, front button style, and a combination type for each with flip clips.
Fourteen lactating females wore the nursing bras for a continuous period of time and compared them for size fit and ease of breast feeding. Nursing could be easily started when wearing either the crossover style or the front button style, but some found the opening and shutting of the flip clips too inconvenient for use.
Product tests showed that there was no mention of under busts but only the top bust range on most of the size tags, a lack of uniformity in the size of the individual finished bras, shrinkage after frequent use and laundering, disconnection of straps due to deficiency in sewing, and impairment of tensile strength in the under tape after approximately 15 uses. These results show that the durability of nursing bras is insufficient.
