I agree completely with what has been said. You've been given good advice already IMO. Since I am in school studying to be a designer (not for apparel, the kind of designer clients hire to solve problems and create identities for them and make visual messages, etc.), I thought I would share some of the ways we are taught to come up with things such as brand names or marks, or ideas for a project, etc. Usually you start with a brief from the client, but since you are your own client, you have to do it yourself. So write yourself a brief. That is like the story of your company. Who is it for, what is the essence or tag-line, who would be the face of your brand, what is your brand's personality, what section of the market do you hope to attract, include any other research in the brief (other research might be about your inspirations, target consumer, fabrics featured, anything). One suggestion I found was to write a story as if you are giving an interview to the Wall Street Journal (or in this case maybe Vogue, W?) one or two years from now. this might help you visualize and articulate what you want your brand to be.
So then once you know what mood and personality you want to portray, just brainstorm madly and quickly and divergently (like try to think out of the box). Don't judge any idea even if it seems completely lame or already done or horrible or impossible or crazy. Just write it down on a post-it note and go through like a whole pad of post-its in as little time as possible. Like at least a hundred. Then pick maybe three ideas that stand out and communicate the brief or story you wrote the best. Develop those by trying different variations, combinations, etc. You can even go through another pad of post-its using those best 3 ideas as a point to diverge from. It's probably similar to how you come up with ideas for garments, but I wouldn't know.
I think in a nutshell, the key to coming up with good ideas is to diverge a LOT. ANd then converge to find the best ideas and develop those.
This works for finding a name, a logo, elements for a mood board for your next line, solution to problems that may arise in your business, anything really. I think the key is that a good brand will have a cohesive name, typeface, logo, and product. They will all reflect a common attitude, so what is the attitude you want to reflect?

I know you were only asking about the name, but in order to decide on a name, you need to have a strong identity for your brand. Even if you don't physical have everything made, you ned a strong visualization of what your brand means in your head at least. So you know what you are trying to communicate. Also, branding is sooo important since today's market is so competitive and volatile. Without a strong clear identity, the consumer will forget you or be confused and you'll be lost in the shuffle.
eta: I hope I didn't come off as trying to be a know-it-all. I am still a student and no expert but just wanted to share things I find helpful that I'm learning in school.
Also fast consonants sell, they are manic, but fun.
