Absolutely not. Go by the size chart online which shows fairly accurate measurements for each item, NOT your body size. I wear a US 14 and 2 XXL tops I ordered were skin tight [a 3rd XXL top was loose!].
Sizing is at least 2-3 times smaller than we are used to
That's not true, you need to order a size larger than what you wear.
