* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.
Btw, the size nomenclature has changed for Bra Tops. Here's the conversion:
XS=0, S=1, M=2, L=3, XL=4, XXL=5

I was looking for a bra that I could wear under a navy cable knit sweater that wouldn't be noticed - the sweater has a peekaboo quality - this bra is perfect. Also wanted the bra for low impact workout and or sleeping in. Met all goals!!!! great quality and fabric

I'm in love with this bra! It totally supports my massive boobs - I'm a 38DDD - yet is so comfortable I actually fell asleep in it yesterday and didn't even notice. It's always been a challenge for me to find a bra that does the job, isn't padded - I don't know why anyone thinks that someone who's a 38DDD would want padding - and doesn't make me feel like a schoolmarm. I'm buying more of these, as soon as I'm done writing this review!

The only reason for the 4 stars instead of 5, I just wish it was a little softer. Otherwise looks great!

If I were any bigger in the band or cup, the 5+ wouldn't fit me, but it happens to be perfect (I'm at the loosest band clip and the cups are just big enough that they hold in my boobs without them spilling out). I'd love for it to be more size inclusive for other larger bodies —(we also want thin minimalist bras like this!) and they are nearly impossible to come by in our size. I guarantee you'd sell out if you offered more sizes!
