I'm writing a detailed review because I don't feel like there are enough for us when we're buying bras! :)I'm 5'2 about 140 lbs (maybe less but not by much) and a 36DDD. I ended up getting the XL. I can definitely wear it and I'm keeping it, but I think it actually is a tad big. I'm on the very last hooks so as it stretches I won't have any ability to tighten it. I think you're supposed to be able to comfortably put it on the first hooks when the bra is new. That way you can go up to the next hooks as it stretches. Just keep that in mind. It also bows out a little on the sides of the cups near the front of my armpits. You can't see it through the shirt though and I just tightened the shoulder straps with only about an inch left of the strap to help minimize this.The thing I LOVE about this bra: I NEVER have to adjust my bo*bs after bending over! When I tell you it's taken me weeks to lose my habit of automatically going to put them back in my bra because I've had to do that my whole adult life, I'm not kidding.It's also comfortable. I was really surprised about that.I typically like to "hide" the size of my chest and this bra does NOT do that, but they look really nice in my shirts. I'm going to try a large when they're back in stock. I'll update about how it fitsUPDATE: I bought the black in Large and it's a little different from the XL. The straps are skinnier and there are only 3 hooks in the back instead of 4. It feels different as well. I actually really like the fit of this one better. It doesn't bulge out on the sides as much and still keeps me from spilling out of the top. I wish I had returned the other one now!Happy shopping :)
