Based on their descriptions, both the Logan and Contrast bras say that they have full coverage with better support for larger cups. I'm a D cup and I've tried both the Logan and Contrast bras. I found that the Logan bra didn't have enough coverage: my breasts were often spilling over and I had to re-adjust the cups constantly. The Logan bra also seems to flatten breasts and push them to the sides, which can make breasts look odd under certain outfits.

In my experience, based on the sizing chart, I would recommend the Logan bra for people who are on the smaller end and the Contrast bra for people on the larger end. For example, if MY's size chart indicates size medium for you, buy the Logan bra if you are a C cup or the Contrast bra if you are a D cup (like me).

Had to return this item because it was too large. Where another item fit perfectly in medium, this one in medium was way too large.
Great fabric ans style though!

I was skeptical when I first tried on this bra. I had some trouble getting the straps and band to work for me, and was afraid that I had gotten the wrong cup size. I got a size XS instead of my usual S, or 32C. The size chart on the website mentions that an XS would fit AA-A cups, but there is more material on the cups of the Logan bra, which is what made me to go down a size.

After some fidgeting with the straps, and some wear, the Logan Bra molded to my body perfectly, and I am very comfortable in it! I also really love its versatility : being casual and supportive enough for every day wear, but also sexy because of the mesh «3

I bought the Logan in dusty rose, hoping that it would be less visible under t-shirts than my black contrast & emery bras. It is! I have the contrast bra in an M and the emery in an S. I bought this in a S and it fits great! Because of the angles of the seams, if I wear a shirt where it can be seen, it’s obvious that it’s just my bra and not my nipples (the others can make it look that way). I I know that’s a popular look, but just not for me :)

This bra is comfortable and lightweight, and I love how feminine it looks. It’s my go-to for day and night, and I will definitely be buying this style again. I bought an XS and wear a 32A, and it fits like a dream.
