Just screwing around with costume designing after playing some dynasty warriors 7 XL.
This attire is actually her Tsong Lakes Uniform, the one she wore before she heard the hero's call at the Tavern. She doesn't wear her lotus hair accessory while in uniform, the monks believe it to be an infringement of dress-code, but allowed her to keep the hairpin as long as she didn't wear it during training.
