Thank you all very much for your help with wireless bras. For the moment, I have rounded up a bit of a collection and have some reviews.

I'll start with the boringest one. Pic 1, fruit of the loom. Bought for work, because I don't care about pretty at work. Whatever I wear to work is at high risk of being utterly annihilated by the rough and dirty nature of work at a produce stand that moves a lot of firewood too. It has been worn already, and it is comfortable, it provides good support, and the color won't show much dirt unless it's an egregious stain like blackberries or something. And yes, that is a concern for undergarments at work. I have wound up with asparagus in my pants, blueberries in my boots, and spinach in my bra--all in the same day. I wasn't a fan of the fabric, because it actually makes me feel like my hands are rough like a farmer or lumberjack (occupational hazard, I guess, I get that from most satin-y fabrics). If it didn't make my hands feel like they were snagging the fabric, it would be a nice material. It certainly suits the function, and doesn't bother me once it's on and I don't have to touch it with my hands.

Pics 2 & 3 are Emporio Armani, picked up for a song at Amazon. The blue one will be for work, the black one for not work. I've worn the blue one, and I liked the fabric, rather t-shirt-like or something. It's padded or molded or something, with some structure to it. The padding will be nice come cold weather, I know y'all know what I'm talking about Good support, I'm a fan. Good value for the price I paid.

Pic 4: b tempt'd by wacoal bralette. This isn't a bralette, it has clasps like a bra. The material is sports bra type fabric, but not compression like my last sports bra from wacoal. I like how this colorway looks like armor or something from a GOT or Witcher costume. I very much like this one. It's not as supportive as the others, but I don't necessarily need it to be. It's comfortable, it looks cool, I like it a lot.

The purple one (pic 5) is wacoal, I have yet to wear it because it is not for work and I get very few days off work. It's wacoal, so I expect I'll like it well.

Last, my favorite of the new additions, pic 6. First seen as I was perusing the Nordstrom site. Loved it in pics, found it at a major discount on Amazon, in a colorway I am obsessed with. Wore it today and I love it. It's a bra, but feels like a bralette in spite of the clasps. It is so stinking comfortable, it's super pretty, it's supportive enough, I'm wanting to get it in other colors in the future (pics 7-10). Big winner, love love love it.

Also under consideration for future purchase: lively, icebreaker (merino wool blend, great for work in winter), and more wacoal.
