    I'm in love!

    I got the Sieve Racerback and Triangle Bras. Size 5.

    I'm in my first week with these beauties and so far, I do believe these are the most comfortable and well- fitting bras I have ever owned. I can't wait to try them out a bit more. See how they hold up with delicate washing over time. And will likely be budgeting to grow my Negative Underwear collection.

    Negative starting to cut corners.

    I've been purchasing from negative underwear for a few years now. I wear either a thong, bra, top, cardi from them every day of the week. However, as the company grows, I'm a little afraid that they are starting to cut corners on fabric and design aka the luxuries that push the prices so high. I very much hope I'm wrong. But to the review:

    Have you ever just not been able to find that one item that would tie your closet or outfit together, but your know it must be out there?

    I have been a huge hunt for triange raceback bras in response to this existential question : what do you wear under raceback tanks (ie Citizens of Humanity) if you are trying to not go for a the "headlights are on" look that day (perhaps because ya know, the office), don't want to deal with sticky boobs, and don't want a raceback sports bra sticking out from underneath!?" Seriously, no one on the internet knows. THAT SAID, after trying on this bra, it does seem to be the best option... barely though. Here is an overly thorough review from a girl who just has a dream that one day she will wear a tank top with an invisible bra under it.

    CONS

    1. Using the Isabel Citizens of Humanity tank as an example, the edges still peak out through the arms holes. Isn't the purpose of the construction of this bra to be a little less visible? Could a version possibly be made with just a little less fabric on the triagles, at least on the sides facing outwards to provide a little more privacy.

    2. In addition, the top of…
