TL;DR

Very plus size friendly OP by western indie brand Kyoko's Closet by Ichigo Black (A Black-owned, lolita-inspired indie brand in Massachusetts)

• Official Size: XL (B 40-42in W 36-38in H 42in) (see reference link for more info)
  
• Tailored to my measurements: B 42in / 106cm, W 34in / 86cm, H 40in / 102cm
• Could stretch ~15-20 cm more and still fit, torso very stretchy/thick material
• Elastic waist, waist bow, and sleeves
• The bodice is made of a different material than the sleeves and skirt but there's no color difference
  

Waist bow is detachable and is attached to an elastic belt which is secured around the waist with snaps (you could use it for other dresses easily), apron is NOT removable

I ordered this dress in my early lolita days and it's not really my style anymore. It's a very comfy dress that would lend itself well to OTT / decora accessorizing but my wardrobe is taking a more classic spin. I've worn it only 2-3 times and I think the colors are relatively easy to match (if you search for menhera accessories you're likely to find a similar color scheme). I think this could go either in a Maido or Nurse direction, but the bear gives you some sweet potential as well. I've included some photos of how I've worn it to give you an idea of how it fits. Accessories are not included in this price, but if you're interested in a bundle feel free to message me.
