They don't need training

Amanda Hess has a Slate article about pubescent girls:

When a girl becomes a woman, she embarks on a wondrous journey of growth, self-discovery, and horrific training bras. The first bra-buying outing is a tweeny shop of horrors: Behold, the dull cotton bra-let with a seam down your nonexistent cleavage; the shapeless sports bra with conspicuously cutesy detailing; the padded, push-up number that appears to be compensating for something. Enter Yellowberry, a new company that just raised more than forty thousand dollars on Kickstarter to make bras for girls aged eleven to fifteen that are (assuming Mom voice) actually really cute! I talked with Megan Grassell, the eighteen-year-old founder of Yellowberry (and a high school senior in Jackson Hole, Wyoming) about the indignities of buying your first bra, the merits of a colorful strap, and how she came up with an elegant name for a puberty accessory:

Slate: When did you first become aware of the great training bra problem?
Megan Grassell: Last year, when my sister Mary Margaret was thirteen, we went shopping for her first bra. We scoured the mall, and couldn’t find anything that would fit her­— nothing cute or fun, anyway. I thought, “this isn’t right— you’re either being sexualized or stuck in a jogging bra, and there’s no in between.” I just couldn’t let it go. I thought, “someone should make a better option for girls.” So I did.
Slate: I’m 28 and I kind of want to wear these bras. Is that bad? I think it’s hard to find a good bra that’s not sleazy and is comfortable as an adult, too.
Grassell: I love these bras! Not to get too personal, but people keep talking to me about bras, so I have no filter at this point: I wear a 34B and I wear a size large in one of the styles. Comfortable bras for women like me do exist, but it takes so long to find them. I might come out with some styles for older women at some point.
Slate: Am I right that these bras are for girls (or women!) who are not super developed?
Grassell: Yes. That’s something I need to think about moving forward; making styles for girls who are bigger-busted and need more support.
Slate: Did you talk to girls about their feelings about bras when you were developing the company?
Grassell: I talked with a lot of girls, and their parents. I’m not sure twelve-year-old girls are saying: “These bras are being pushed on me with all of this sex!”, or whatever.  But when I was going through the prototyping phase, I recruited my sister and a lot of her friends to try the bra on or wear it for a day or a week— at soccer practice and in class— to make sure that they’re super-comfortable, which I think is the most important part for the girls who are actually wearing them. I look at the company as having two customers— the girls that wear the bra and the mothers who actually buy it. And I think a lot about Yellowberry will resonate with the parents— the mother who doesn’t want to rush her child into growing up, or who didn’t have an option like this when she was very young.
Slate: Why do you think the first bra-buying experience can be so unpleasant?
Grassell: Oh, it’s so awkward. Your body is changing, and it’s difficult for anyone to fully address that, particularly in the form of a new addition to your wardrobe. You’re in a vulnerable position when you go to the mall and you’re being measured, and then when you go to school and everyone can see all of a sudden that you’re wearing a bra.
Slate:Your bras are all very colorful. Is the idea to just put it out there? Yes, I am wearing a bra!
Grassell: The two styles I have right now are super-colorful, so if you’re wearing a white shirt, you can see the bra through it. We’re working on putting more out with different shades of beige, mocha, and white. It’s definitely true that in the summertime, Mary Margaret may not always want to go around in a tank top that flaunts her pink bra. But it’s like anytime you buy underwear that’s really cute; the point is that it’s just fun to wear and put on, even if no one else is going to see it.
Slate: The name Yellowberry is evocative of adolescence; it’s the fruit that’s not yet fully ripened. Was it difficult to figure out how to brand a product around puberty without being too obvious?
Grassell: Yes. I look back on this now, and I can't believe this almost happened, but I’m from Jackson Hole, and my mom started thinking of ideas that could subtly make fun of both Jackson Hole and bras. She wanted to call it Holey Boobies. I thought, “Well, no one’s going to forget that name.” But it made me uncomfortable whenever I told anyone about it. Eventually I was like: “Mom, we can’t do this. We just cannot do this.” I realized we really didn’t have to say “boob” or “bra” in the name. People would figure it out. I think that if I was twelve and had to buy a bra called Holey Boobies, the experience would have been a lot more traumatizing.

Rico says he's way too old to be talking about this...
