Black leather look leggings by maternity clothing brand Seraphine in UK size 8. 

Please note due to my petite frame, I had these shortened to an inside leg of approximately 26.8".

These were bought new from Seraphine and were only worn a handful of times so are in great condition, perfect for dressing up or down. 

Composition:

Front: 100% polyester
Reverse: 65% viscose, 28% polyamide, 7% elastane

Any additional questions, please PM me. Happy to help :)
