I need your honest feedback. I have a YSL Muse bag in chocolate and would like to dress it up with a little Hermès pocket square or twilly. However, is it considered "A-OK" to mix brands like that? I checked with the YSL boutique in NYC and they have no small scarves at all so my only choice is to go with a different brand. And for me, Hermès is "It" when it comes to scarves. Your thoughts ?
