GOOD SHII for some reference, I'm 5'3"-5'4" -ish, around 110 lbs, and my boobage is 36b. I ordered a medium, I'm usually already a US small-medium with adult clothing, so normally anything online or using Asian sizing medium is my go to. It fit perfect for me, it was snug so I wouldn't reccomend medium if you might be a little bigger :3 this outfit is a more tight-fitting one than the other Mista listing, which is obviously a more stretch sweater material. But this material is stretchy too,just in that cheaper mesh feel, but I honestly like it like that. I might upgrade later in life to an actual Mista sweater and jeans n' all, but I actually really dig the stylized lines on the hat, sweater, and pants. It's what I go for when I do my Jojo cosplays anyway. I'd go as far to say that I prefer this hat out of a lot of hats I've seen for Mista, as anywhere it touched the face, there's an adjustable wire. I reccomend a wig cap if you want to wear the hat accurately, but I'll warn that it'll likely show in the back as the hat doesn't completely cover the back of the head. This isn't much of a problem for me as I'd say my hair color and texture matches hoe people headcanon Mista's hair to be, so I pin the edge of my cap higher on my head and expose a bit of my hair where the hat is open. A warning though, boob's or no boob's, the lines were the chest is stylized to be is, like, super high, so I think even if you bind or wear a body suit underneath, it's gonna look a little silly from the inaccurate anatomy. But I honestly don't think it's too bold to notice! Really the most eye catching parts of the outfit is the hat and pants, it's kinda funny that no one really notices the chest error. I literally adore this costume and, with how I tend to be with my cosplays, I pick and choose random pieces from it to wear around the house or anywhere local (for this, it's his hat lmao. It's very comfy and it's been ironically a hit for the normal non-jojo watchers LOL). And if I can note the customer service real quick- I ordered this as express shipping around... I think a weeks notice, or even less, for an event I was going to (which I ended up not going to because I got super sick, but spoiler alert, the costume made it in time anyway haha!) And the customer service was really nice in explaining to me what to expect with paying for express shipping. My expectations were exceeded since Mista actually arrived a day early to when I needed it. For refeence, the scale of tike I was given was 3 days, the day I needed it being the last day of that time frame, so it came in on the 2nd day it was expected to arrive! I'm still sad I couldn't wear it for what I needed it for, but I've gotten better and I definitely plan on wearing this for other anime events. Who doesn't like Mista, eh?
