Not sure how you see this working as a brandable, never mind a perfect brandable. Maybe if it were BoutiqueN - or possibly even Boutiq. But a misspelling of an English word with a random letter at the end that renders the word unpronounceable as a single word in English... I am not even sure how you would pronounce it as a word+letter ("Bow-tick-n", "Boo-tick-n" ??). If you try to have it pronounce as "Boutique-N", then nobody will remember the spelling of it due to the misspelling...
Unfortunately, I'm not see even regfee on this - $0 across the board IMHO. As it was regged yesterday, I recommend you grace delete it and get your money back...
Hope this helps!
