I've been looking at the Leo in gunmetal and black velvet. Kind of leaning toward gunmetal since everything else I'm wearing is black. I want something large enough to carry my iPhone 6+ and other necessities without having to pack things back in after I've retrieved something. I'm kind of avoiding glitter and crystals, afraid of snags in my crepe dress. Hesitating on buying, wondering if it will look too casual, especially with the zipper trim, and/or too big? I'm not much of a clutch person, so may not use it much, although it could be repurposed for an iPad case or something. Appreciate any opinions, thank you.
