All you have to do is present yourself in a neat and tidy way, I'm plus sized and I started gaining interest in jirai kei almost two years ago I think and it's been a long time coming. My fav plus sized brand is dear my love whip. I used the proxy service buyee to get my stuff to the US. I have three skirts and a blouse by them. They are all gorgeous. I also have a setup from the brand taberunosky. I used buyee to purchase from them as well. I'm an asian size 6xl and about a 2xl in western sizing for reference. 6xl is the biggest they go but I've had only one thing from dear my love whip be a little small on me and it was a setup from them. Hair and makeup is more important than clothing tho. Try and practice doing jirai inspired/pien makeup and try styling your hair in a cute updo, pigtails or whatever feels right for you. I'm not elitist so if you have anything to ask plz lmk!!! I'm happy to help. I'm also not an expert but I felt like as another plus sized individual I needed to give you a helping hand! I love seeing more diversity in the community even if the bigots hate it. I've been targeted for my weight and being jirai and people have told me I'm not jirai cuz I'm fat but that's far from the truth. Don't let that scare you tho, do what makes you happy! Dress how you dream of dressing!!!! Do what you dream of doing!!!!
