[Xishi cosplay] Honor of Kings Mermaid's Song: Fitting Details and Honest Review

It's been a while since I received this Xishi Mermaid's Song set, and today I finally found time to put on the complete wig and accessories for a quick look in front of the mirror. I've seen many fellow fans share this look online before, and the overall blue-and-white color scheme is truly eye-catching—perfect for summer or shooting photos with a refreshing style.

When unboxing the package, the most immediate impression was how neatly each part was individually packaged. The main outfit features a white base adorned with layered, lightweight teal-blue and white ribbons, giving it a rich sense of depth. The halter-neck design is paired with a metallic-textured badge on the chest, which is quite delicate in person; its gold glitter creates a lovely reflective effect under light.

First, I tried on the wig: long silvery-white hair that is very smooth without major tangles. The dragon horn headpiece on top isn't heavy enough to weigh down the hair; it has a firm, semi-transparent resin texture when squeezed, and once secured with hair clips or the included elastic band, it sits sturdily on top of the head.

When putting on the main dress, adjusting the waistline was the key focus. The fabric feels soft, but the waist tailoring is clean; fastening the sash at the right position clearly defines the waistline. The short skirt hem makes the legs look very long, ending right at mid-thigh, creating a dynamic, flowy effect when walking.

A pleasant surprise with this outfit is the sleeves, which feature an adjustable design. The cuffs are wide, consisting of an outer white gauze and an inner teal gauze, feeling loose when worn. However, because there are hidden adjustment buckles near the wrist and shoulder, you can tighten them to fit your arm, ensuring they won't slip off or feel uncomfortably tight during movement.

Next, let me talk about the footwear, which is the leg covers photographed separately in the picture. In cosplay outfits, shoe/leg covers are often a pain point—too soft and they lose shape, too hard and they feel stuffy. This pair is made of glossy white faux leather with blue-and-gold patterns, featuring a zipper on the side that operates smoothly. Beyond being easy to put on and take off, the key is their great wrap and fit; they don't slip down while walking and have high stiffness that makes the legs look straight.

As for the overall look, this off-the-shoulder halter style is flattering on the shoulders, and revealing the collarbone slightly gives a lighter appearance. Although white is the dominant color, accents of teal-blue and gold thread keep it from looking bland. In particular, the sleeves' design—longer on the outside and shorter on the inside—provides a great feeling of extension whether hanging naturally or lifted slightly.

Since I took selfie photos in the mirror with my phone's front camera today, I casually adjusted my outfit to ensure the dragon horns and chest badge were centered in the frame. The long bangs on both sides of the wig rested nicely on my shoulders, blending seamlessly with the outer white gauze, making the overall look quite harmonious.

I previously saw many players saying that anyone wearing this outfit looks ethereal, and now trying it on myself, it really is true. The cut of the outfit leaves ample room for movement—for instance, the sleeves are long but don't get in the way of holding things or striking natural poses. The waist strap is also tightened according to one's own body shape, making it snug and comfortable without feeling restrictive.

Lastly, let me talk about the fabric materials. Besides the outer white gauze, the teal layer seems to be a semi-sheer organza with a bit of structure, allowing the skirt hem and sleeves to hold a puffy shape. The stitching for the gold foil stripes and blue piping is quite neat without slanting or skipped stitches. For regular cosplayers, managing this fabric isn't too difficult—just make sure to hang it properly during storage to avoid creases.

My main takeaway from this fitting is that the overall completeness of the outfit set is very high, requiring virtually no additional modifications. From the wig to the costume to the leg covers, everything is basically ready to wear straight out of the package. I'm already planning to take some outdoor photos by a river this weekend, using natural light to illuminate the gauze fabrics, which I expect will look even better than indoor mirror selfies.
