    WOW!

    I will admit that I had rather low expectations for this bra, other than being something "pretty" in my lingerie collection. But "WOW!" it is wonderful. Very pretty, as expected, but also SO comfortable, and also, supportive! I am a 34D and had imagined that this would strictly live at home for lounge wear. But it is also supportive! I will absolutely be wearing this out and about. And oh my, it is even prettier than I had hoped for. I bought two (slate and black) as it was on sale. Now I want one of every color!!!

    Not my fave

    I have many items from NU - this is the first one of this line made out of the sieve fabric- it’s just not my fave, not as soft as I thought it would be; if fabric was different, I would’ve kept it

    Sieve Bra Top in Navy
    Rated 5 out of 5 stars
    Great Design

    So comfy, and liked the lack of pressure on my shoulders (sensitive from a previously broken collarbone). The cut is lower than I thought and I liked it for under v neck tops, but had to get a size up after trying this one; the neckline pressed against my chest, which is shallower at top than at bottom. Overall will order again.
