Having bought, worn, washed and re-worn my initial 8 pairs, I must say that viccel is good value for money. I haven't had problems with stretching, them winter weights still wear good. Most of the darker shades (blue, red, green and there's a mustard colored one, can't recall the name) are easy to match. I have the same problem as lachyzee with the baby pink (as well as a baby blue) - less muted than what I thought it'd be.
My only other minor gripe is the scratchiness of the hem - occasionally feels like a burnt ring of plastic stretched around my upper calf/knee area. Obviously I don't have this problem with my mazerins, marcolianis etc. etc. But then again, I pay alot more for those, and so I can't fault and should instead applaud viccel for providing a decent, well-priced product with a good range of colors to choose from.
