词语含义原指天上神仙穿的衣服因不是针线所缝,所以没有衣缝。后用来比喻事物的细致周到,严密完备.找不出什么破绽。成语出处五代前蜀·牛峤《灵怪录·郭翰》:“郭翰暑月卧庭中,仰视空中,有人冉冉而下,曰:‘吾织女也。’徐视其衣,无缝。翰问故,曰:‘天衣本非针线为也。’” The original meaning of the meaning of the word refers to the gods dressed in heaven because the sewing is not sewing, so there is no clothes stitching. Meticulous things after the meticulous and thoughtful, well-prepared. Can not find any flaws.
