Body Measurement Instructions

Please stand naturally and keep your body relaxed while measuring. Use a soft measuring tape, held snugly against the body without being too tight. Record the following measurements:

  • Bust: Wrap the measuring tape horizontally around the fullest part of your bust.

  • Waist: Measure around the narrowest part of your waist, typically located between the bottom of the ribcage and above the belly button.

  • Hips: Wrap the measuring tape around the fullest part of your hips, usually across the widest point of your buttocks.

  • Shoulder Width: Measure straight across from the outer edge of one shoulder (shoulder bone) to the other.

  • Sleeve Length: Starting from the shoulder tip, measure down the outside of your arm, passing over the elbow, to the wrist bone. Keep your arm relaxed and straight at your side.

Great Out of the Box Option and Higher Quality with only Minor Flaws

TLDR: Overall, this is a great cosplay for the price point with a few minor flaws. As far as store bought cosplays go, I’d give this a 10/10. I was pleasantly surprised with the quality and looked even better after steaming/pressing.What I liked: The jacket felt more substantial and the detail was great. The shorts fit well and the stitching and embroidery was higher quality than I expected. The attention to detail was really well done, even down to the glasses and pearl earring included. Overall, it’s a great cosplay for the price. PLEASE steam store bought cosplays and they will look 10x the price, I promise.What could’ve been better: My biggest issue was the shirt, while it fit well, it was difficult to move without untucking it and there wasn’t much mobility. You have to pad the chest area to get a better fit, but it still pulls around the waist and makes your midsection look a bit larger than it really is (fitted shirt problems). The pinks were more fuschia/vibrant than the character design, I may replace in the future with a more muted pink/purple fabric. The stockings worked well, but the seam was very visible and they started to get fuzzy in high rub areas (ankles, thighs, etc). The boot cover was great, but I have longer legs, so I had to wear it lower to connect with my boots. The thigh strap kept falling down and tore a little bit at the knee.If you’re looking for an out of the box cosplay, this is an absolutely great option. There are minor flaws, but that’s to be expected at the price point. I was pleasantly surprised at the details included and the overall quality. I’ll definitely be using again with a few minor tweaks.

Great, but not right gloves…

The outfit came amazingly fast and the fabric fits great! My only complaint is that it came with two gloves for the right hand, which is really unfortunate since now I have to buy leather gloves to compensate!

Fits well

I bought a size small and I'm 5 foot 3 inches and it fits great though it's a little snug in the waist it's not annoying. The quality is way better than I expected and it's pretty comfortable. It got here super fast.
