In short, no. Depending on how often you wear your kilt, you'll eventually want to get a leather targe sporran in black or maybe a brown flap-front sporran. I've got 4 sporrans including: brown embossed flap-front leather, black targe top-cantle, medium gray top-cantle rabbit fur, and a white top-cantle rabbit fur with black tassels. The medium gray replaces my black top-cantle rabbit fur which was my go-to sporran for years. For the casual outfit you're wearing, your sporran is fine ... except for the white tassels. I'd dye them black to match the sporran (you can usually undo them from inside the sporran through holes hidden by the fur). The top-cantle opening is so much easier to get in and out of and it's easier to fasten back up. You really only need a leather sporran if you're going to work a Highland Games or volunteer at an event where a fur sporran might get messed up. Targe sporrans are a good compromise there and they're generally less expensive too. Good luck.
