I normally wear a 14/16 top and ordered the 2XL. A 2XL would normally be too big for me but another commenter said she is 220 lbs and the 2XL fit her and I weigh about that also so I went with the 2XL. It fits great! I got white and it's slightly see through - I have a red tattoo on my shoulder and you can sort of see it through this top. But you will need to size up a bit - if I hadn't read the other comment I would've bought an XL and it would've been too small.
