Photographing jeans

This is something i’m still struggling. I’m not satisfied with my photographs but i’m trying to do better. Right now i’m happy because colors on photos are practically the same as on real jeans because i’ve invested in proffessional lights, but shape does not look so good when lying flat on the board. I’m planning to invest in future into mannequins. Anyway, real jeans are way much better than shown on photos, that i can promise.
