Narrative:
ZAB asked us to descend to cross elloy intersection on STAR at 10000' at 250 KTS or less. I read back clearance and when we reached 10000'. ZAB said he cleared us to 11000'. I remarked that I read back 10000' and it was confirmed by captain. The F/east thought so too, and it was set in altitude alerter. We climbed back to 11000'. Readback was not corrected by controller on initial clearance. I believe I even said it correctly as '1-0-thousand' with no correction by center.
