So, I've found an unlined bra that actually technically fits well! The band is small for a 30, shoulder straps are quite stretchy and comfortable, the wires are wide enough, and the cups don't wrinkle or dig in. (I assume the stretch lace at the top of the cup helps greatly) The nude color is a nice match to my skin tone, and the fabric has a subtle geometric pattern which I like. Unfortunately, the gore gores me, (they all do) and the fabric felt a bit itchy. I've never experienced this with a bra and, I wanted to scratch all day! Hopefully another wash or two will fix the itch.
Good: -Colour blends well with the skin. -Thin sheer material does not add bulk. -The shape of the cup gives the breast a natural look, round at bottom. -Feels comfortable to wear.
Bad: -The straps at the back are quite far apart. I'm not sure if the straps will slide as have not wear out yet. -Centre cup separation quite wide. -Need to arrange the fabric of the cup to prevent wrinkling so it won't show through the shirt. -Band quite tight, not sure if will loosen after wash. Have just tried upon receiving the bra. -Not sure if nipples will protrude through. Needs to give it a trial first.
I'm starting to like unpadded bras since they're easier to nurse in. This is a nice black bra with delicate lace at the top. Though honestly, I'm not too keen on the sheer fabric at the top of the bra. It fits well, though there's a bit of wrinkling going on at the top of the cup.
The straps are a bit thin in my opinion. It also gives me an east-west appearance.
