Seven items come with Mutsumi Full Set: a pinafore dress, shirt, collar bow, apron, socks, satchel and bunny charm. The set costs $66.99, with XS, S, M, L and XL available. A wig and shoes require separate purchases.
This is Wakaba Mutsumi’s outfit from the Arknights crossover with BanG Dream! Ave Mujica. For the band’s quiet guitarist, the blue pinafore offers a different wardrobe direction from school uniforms or stage clothing, with the apron and little bag giving the outfit its particular character.
The pinafore has details worth leaving visible
The blue dress establishes the main shape, but the lace-up front deserves attention of its own. When arranging the layers, leave that detail readable rather than letting the bow or satchel obscure it. The apron’s ruffle adds another point of interest lower down, balancing the detail near the neckline.
Polyester is the listed material. The shirt sits beneath the pinafore, so sleeve placement matters alongside the dress itself. Give the cuffs a moment of attention when dressing; small details can disappear in a photograph when the arms stay pressed against the torso.
Three charts for Mutsumi’s layered outfit
Compare the dress, shirt and apron measurements together. In M, the dress lists an 84–88 cm bust and 66–70 cm waist, while the shirt lists a 90–94 cm bust. That difference matters: choosing by the shirt alone could overlook the narrower measurements of the garment worn over it.
The M apron also lists a 66–70 cm waist, matching the dress’s stated range. For length, the dress chart runs from 85 cm in XS to 93 cm in XL. Use those figures to judge where the skirt will fall on you, alongside the bust, waist and shoulder measurements.
For the M shirt, the chart gives a 54.5 cm front length, 58 cm sleeves and 37 cm shoulders. The M dress lists a skirt length of 89 cm and shoulders of 31 cm. These separate shoulder figures are another reason to check both layers when comparing the set with your measurements.
These are garment measurements, with a possible 1–3 cm variation from hand measuring. Height ranges provide another reference, but compare the individual garment dimensions before settling on a size.
Give the bunny charm a little room
The satchel and bunny charm reward a photograph that includes more than the shoulders. A waist-up or full-length frame can show how the bag sits beside the apron. Angle the bag toward the camera enough for the charm to remain visible, without drawing it across the dress’s front detail.
Mutsumi’s quiet manner also gives you a useful starting point for posing: relaxed hands and a reserved expression. There is no need to build every picture around a guitar. The supplied accessories already give your hands something to interact with.
