At first I was a bit wary of them because of the high arch and tight straps which sit lower than my normal flip flops, but these grew on me. They're heavier than I expected, which probably accounts for the lower strap line, but they're not uncomfortably low or heavy, so neither is a con. The leather is soft and forms quickly to your foot. I wear an 8/8.5 and originally ordered an 8, but they were too small so I got a 9. They fit great with a little room around my feet. My flat feet are happy in these arched sandals and I wear them nearly every day now. Insta-fav!

I bought these on recommendation from my boyfriend at the time. They looked cool and have great arch support, so I figured it'd work out. Alas, they are not the sandal for me. The soles are hard and the heel was really uncomfortable. Meaning, my heel was sore at the end of the day from wearing these. I'm not sure if it's just because the sole rises up on both sides of the heel or what, but they're mighty uncomfortable for my foot. The arch support is great though. The straps are fun to play with, but they do have to be adjusted every time you put them on because my big toe ends up getting bothered. Good luck with them though. He loves his Chacos; I just wish mine had worked out.

At 5'6, 135lb with a 34/36A, I figured the medium would be just fine. However, because of the cut of the bra, it was tight under my arms and cut in a bit more than I was comfortable with. I sent it back and got the large and have been happier with it. It sits about mid-rib cage, doesn't ride up at all, but is still a little higher under the arms than I'd like. It cuts in a little at the front of my arm pit where that fleshy bit is. But, it's comfortable and keeps the girls in their place, so I'm satisfied.

At 5'7, 140lbs, I figured a Medium would fit fine for me, as that's usually what I wear. No way. Going along with what one of the other ladies said, it would seem that NF expects you to have quite a bit of chest to fill out this shirt. I, unfortunately (for them?) do not, so this shirt was baggy and ill fitting. The shirt was rather baggy in the middle as well, which I found odd. I expected it to be a bit more form fitting than it turned out to be. The material is comfy and the style could be cute, but it didn't work out for me.

I got the black bra, which looks like it might have a little different cut than the colored ones. I got a medium, which for a 34A I thought would have been fine, but it was way uncomfortable. It cut up under my arms in the front and back, and was quite a bit tighter than I expected it to be, in a bad way.
I'm going to try a larger size, and different color in hopes that it redeems itself.
