We changed leos in 2007-08 season... GK messed up the next year on one sleeve, but it was still the same basic leotard for 2008-09 and 2009-10. Then, they discontinued our velvet, so in 2010-11, the bottom was nylon for girls that needed new ones (but same style). We didn't like how the nylon looked on the older, taller girls, so the next season, we changed styles. (4 years in that leotard style... first 2 years, we had actual sweats with our logo silkscreened onto them... the next 2 years, we had "real" warm ups from GTM).
In 2011-12, we got a new style, from the GK catalog. The girls picked it out. The old warm ups wouldn't work with it, so we went with basic black GK warm ups. We kept the leo and warm ups for 2012-13, but the GK rep hadn't told us that the leo was scheduled to be phased out... meaning it cost more as a special order in 12-13... AND it couldn't be ordered after December 1, 2012... and we had 2 girls join team in December.
In 2013-14, we HAD to get new leos because of the cancellation of our old ones. We went with AF and also changed our warm ups and bags - we now have "bling" and the whole package (leo, warm ups, bag) is only $250... and, depending on the numbers ordered, it could be cheaper, in which case, the extra goes toward zone registration and meet fees. We have no intention of changing our leotards or warm ups anytime soon.
