Muscle back splice blue/black
The costume fits very well - I chose a design I usually wear and the sizing is very accurate. I think the blue/black side panel is very attractive but the blue doesn't "pop" as much as I would have liked. Nonetheless very pleased.

Really nice colours and design but fabric feels really thin
The design is really nice but the fabric feels incredibly thin. I am guessing they will dry quickly but I am not sure how long they will last.
