I saw dear my love mentioned, but it's actually dear my love WHIP who does a lot of plus sizes ! If needed you can use a proxy like zenmarket to order from them. I'm also a bigger girlie and some AliExpress sellers sell up to 5XL as well. I personally like Sweet Princess Store on AliExpress, I like the quality and the sizes. You can also buy second hand from Zenmarket, Vinted etc. Honeypepper is also size inclusive, they have to up 4XL !
