Pretty sure he means you don't have to wait for an individual to help bid for an item while it's automatic.
The last time I used Zenmarket you could declare your package value with no problem just have to pay a very small fee.
I have some relatively large calves (IMO) with ~16" around and 6.5" hems as mentioned above gives off the leggings effect. If that's your case something that allows for stretch (Cotton/EA blend) would be your best bet.
No problem with 7" hem for boot tuck and cropped pants ftw.
