LLL CRB tank - how do they run sizewise?

[boston340]

How do CRB tanks run?  Do you usually order your regular LLL size or size down?  There are some cute striped color combos in the WMTM section.

I actually size up one as I don't like how tight it is around my stomach. It's very form fitting. Most other LLL tops are tts for me.

I get my normal LLL size. I could size down since they don't have a shelf bra but I like the slightly fitted not tight look for my CRBs.
