I want a super casual large summer black bag and have narrowed it down to two choices ladies: 1) Black Denim XL 2) Noir Mahina XL Just so you have a feel for my exisitng handbag wardrobe, I live in Arizona, already have a chanel GST in Black and the new chanel n/s lady braid tote, so I am not lacking for large black bags, just one that works for summer and is easy breezy beautiful when it' s 115 degrees here! Help and TIA! I have the Mahina XL in Gris and I AM IN LOVE! It doesn't screem the logo, it's quietly elegant Louis Vuitton! BTW, I have a 3 yr old and am a busy stay at home mom who volunteers so it has to be durable, and I don't know how the denim wears?
