I am wearing Sanfenwangxiang's size L. Combining my personal body data of 172cm, 140 jin (approx. 70kg), and a shoulder width of 41cm, this can serve as a direct reference for buddies with a similar body type. The sizing is true to size; for most parts, you can just choose according to your normal size. The main body of the costume adopts a very glossy and highly elastic leather material, and the pants also retain good elasticity. For fabric that is both stiff and requires a tight fit like this, being able to not restrict movement definitely deserves a thumbs-up.
However, I need to specifically point out one thing: with a shoulder width of 41cm, when I wear this size L, the shoulder position does feel a bit tight. Although it doesn't affect my ability to raise my hands or turn around after putting it on, and the overall range of motion is quite decent, if you have a broad-shouldered build like me, I personally recommend sizing up by one size directly, as the comfort level when wearing it will be significantly higher.
The details on the upper body are handled quite well. Thick breast pads are built into the chest design, which has a very obvious shaping effect on the original body curves after putting it on, making the visual look very upright. The head accessories are very thoughtful, coming with a pair of independent grey cat ears. The top of the hat has specially reserved holes to place the cat ears. The cat ears' material leans stiff, allowing them to maintain a three-dimensional shape for a long time without going floppy. The inside of the hat section is supported by hard iron wire, which is extremely practical; you can freely mold the desired curvature according to your preference to make the entire headpiece fit your face shape and styling better.
The lower body is a huge highlight of this costume. The leg sleeves structure visually resembles thigh-high leather stockings, but the surface features a full-embroidery process, which is highly heavy-duty crafting. The leather itself has support while also combining elasticity, making the wearing process very convenient—just pull them straight on. Thanks to the moderate elasticity, the leg sleeves can snugly fit the thighs during movement, making them unlikely to slide downward, while also completely un-restricting me from doing deep squats or large strides.
The armor on the shoulder blades and the knee pads utilize a 3D-printing process. This treatment guarantees the hardness of the accessories and the flatness of the edges, offering high character accuracy. Another accessory with a massive presence is that oversized cat tail. The white-to-pink gradient color scheme combined with the thick stuffing maxes out the photo effects, feeling very weighty in hand.
This time, I also specifically tested the matching shoes. The heel design is obviously sturdier than shoes from most cosplay shoe shops. After putting them on, walking doesn't feel shaky at all; both the slip resistance and support are well executed, making daily shooting walks truly convenient. What satisfies me the most is the shoe upper material, which has an excellent texture and doesn't crease due to performing special movements. This can save a lot of trouble for readjustments during later shooting. The total price of the entire outfit is 769 yuan. From material thickness, the number of accessories, to hardware details, the overall cost-performance ratio is very high, making for a wonderful leather costume special edition review style fitting experience as part of my Honkai: Star Rail cosplay journey.
