    Worn all day!

    Comfortably worn for a full day of travel. (Without wanting ro rip it off the second I got to my destination) The fabric is delightfully soft! The arm area keeps everything all nice & tucked in without pinching. I love that I can adjust from regular to racerback easily. I actually found that I prefer wearing this in 'sport' mode for a nice lift. (You'll find me in a sports bra most days)

    Dreamy and Cute

    This was the style I was most interested in and it does not disappoint. It offers support in all the right places as a 40E and gives some nice shape without the wires.

    The band is pleasantly wider than other bras I've had, AND it doesn't give you backfat bulges, which makes wearing tighter fitting clothes enjoyable again, as I'm not self conscious about my back.

    Number one question I get: don't your girls fall through the hole at the bottom?

    NOPE!

    Not going to lie, had the same thought. The girls don't even think about it, nor have they tried escaping. That hole gives a nice shape and some ventilation for all day wear comfort.

    As stated on another review, you should probably treat your bras better then I do by washing in a garment bag, but if you're like me and anything goes: you'll be just fine, they can handle it.

    This style also has front adjustments and they are dreamy. One-handed adjustments are a cinch with the cool little table on the buckle. I also like the adjustable J hook. Also easily worked one-handed (and undone so you're not trapped. lol).

    This material is heavenly and has ruined me to my other bras. The color does not bleed, nor has it faded. You will forget you're wearing a bra most days.

    Buttery soft, all day wear!

    This bra holds you nicely and is quite flattering. These do have a lot more material than I am used to. The straps are thicker than I would like with a tank top. A 3 hook back where I have never had more than a 2 hook took a minute to get used to. All that said, my straps don't slide down, not because I have them so tight, they make their own indent, but because the shape of the bra does not allow the straps to slip down. The extra material I was worried about showing in tops actually helps to cover up/hold in that problem area where your chest, arm and armpit meet. It is lowcut enough to go with most tops I currently own.

    Overall it is a very flattering undergarment that you don't want to rip off the second you get home. Buttery soft, no uncomfortable wires, the ability to make into a racerback with little to no effort and no digging in anywhere with the strap adjustments.

    A solid go-to bra for larger chests!

    So I've spent a fair amount of time throughout my life looking for the perfect fit. I was always annoyed when people would say to increase the band size and decrease the cup size to get the "right fit." I have always been a 34 DD/DDD (depending on the time in my life), or larger during pregnancy. Bigger chest, not huge around the rib cage. It gets frustrating after a while. Then I spoke with the wonderful women at iteration. They put so much time and effort into getting the correct sizing for so many types of bodies. After trying this bra, I must say - the fit was SPOT ON! It was extremely comfortable and fit perfectly around my ribs without causing discomfort or a gap between the band and my chest in the front (if you know, you know). It didn't matter what activity I did, the fit remained perfect. It was SUPER comfortable, which anyone with larger breasts knows is also a unicorn when it comes to bras. It was like wearing nothing....but with all the support of wearing something. I'm a big fan of the built-in option for the conversion to sports bra and the ease at which it converted. The coverage was just right. Enough to keep me in during movement, but minimal enough where I didn't feel like I was being strapped down or wearing a sports bra. The material is a HUGE PLUS and one of the biggest things I love about this bra. It's so soft and breathable. I tested the bra out during an intense workout, after which all of my clothes are usually soaked. After…

    Never knew what a $68 bra was like...IT IS WORTH IT!

    I have never (NEVER!) bought myself a nice bra. BEEN SERIOUSLY MISSING OUT! So well made, such great attention to detail, and fits amazing. Super comfy, practical but I still feel 'pretty'!
