That Mulberry with the tassels is gorgeous. I LOVE tassels, don't know why. However, IF is fun, and you may really like that. I carried a IF with a funky design for year, and I got complimented on it wherever I went. I still have it too.
The Lanvin is definitely a "lifer" bag, so is the Mulberry- they will never go out of style. The IF bag at the end will date. Its definitely a bag that is stlish and current but will you carry it next year? Saw some of them at Holts and was surprised at how bright they are IRL.
If you want a bag just for this year, go for the IF. If you buy for longevity, then the Mulbery or the Lanvin.
Just my opinion though.
PS. Have you seen the IF bags at Holts?
My vote goes to the Mulberry Araline - I love these bags, I so want one! Second place to the one with the butterfly on the front ( what brand ??) I also have to say that I really don't like the wicker one - sorry!
