Did you ask her because you yourself are going to develop it or to sell it as a domain?
I had to use Altavista to figure out what Couture was and I get it, but why 'klick' as a prefix?
Was ClickCouture taken or what's up with Klick?
I would consider it nothing more than reg fee until I understand what the klick means.
But don't tell your girlfriend that.. Tell her you made a mint from the domain and buy her dinner
gl dude
EDIT: Now I see that
KlickFashion seems to be a fashion magazine and I guess that's where she took the name from. If I were to open up a fashion store or what ever I wouldn't pick a name that is so similar to another company. I don't know how profitable KlickFashion was, since their latest update on FB was 2015 and their site
http://www.klickfashion.com/ is down (at least for me).
BeautifulCouture.com was sold a couple of months ago for 150 USD. Do you consider your name better than this? 10x better than this?
Maybe you can sell it for a profit but there are no $x,xxx waiting under the rainbow
