My most popular colors are white, black, fushia, purple, olive, red and sometimes light blue or light pink. Royal blue, yellow or light green are my least sold. I think I sell more of the bold colors because there are not alot of people that sell them. Most people only carry the lights, so I tend to get alot of business for bold. The sizes I sell the most of are either 0 -3 month or 12-18 and preemie size, during the winter the long leg rompers are big. because I cater to alot of preemie moms from preemie boards is why I sell alot of preemie size.
The interlock prints alot better then the baby rib but to me they both print pretty nice, the interlock to me is just alot nicer of a garment. It is alot thicker and tends to hold up much better then the baby rib. The interlock also seems to run a bit smaller then the baby rib though.
Hope this helps
