I have a black Epi Pochette and LOVE it but I too want the Eva. So my vote is for Eva - it is roomier and I like how you can wear it across the body or on the shoulder
I just got an Eva -- and absolutely ADORE her! So versatile and feminine -- fun to carry. I esp. like carrying her without the vachetta strap, just the chain. I can't say enough about this purse!
