It's becoming more and more acceptable for men to be interested in grooming and looking good in clothing. Finally, women have a place to take their boyfriends/husbands to find jeans that don't have the saggy butt--a complaint by many women I've found concerning men's jeans. It is also a cool place because while you're there you'll notice other straight men browsing clothing. The stereotype is that only gay men know how to dress well and straight men need a lot of help so it is refreshing to see other straight men seeking out fashionable options. Gents: you'll need to get over the whole "this isn't manly" idea when visiting and possibly adjust your perception of what being a man truly is. I believe there is general discontent from certain females that men have gone too casual. My grandma thinks this is a disgrace as men in her day used to dress to impress.
My experience with Blackbird has been from their Fremont location. Immediately this store gained popularity with male friends of mine because at that time there wasn't a true men's boutique that catered to young professional men with an urban twist (not just suits, but casual streetwear)
I first met Suzy the mother of Nicole whom I later met and had a great discussion about brands and clothing. I purchased my first Coal hat there and was later invited to an exclusive sale (windows were covered with paper, a guest list, a bottle of water, and a survey) that was only available to past shoppers. It was at this sale that my Brown Sound jacket was on sale which I spied one of the first times I visited the boutique. I got it for a good deal and have been happy with it ever since.
The staff is really helpful and they make you feel really comfortable while shopping. Plus, they know and love the brands they carry so they can tell you all the backstory behind each brand and if Nicole is there she'll tell you why she bought the brand and even a bit about the politics that went into it.
For a guy who's the least bit interested in dressing well this is a great place to start. Fellas, there's more options out there than fleece and bad denim!
