I really love the original Viva La Juicy fragrance but unfortunately it doesn't mesh well with my own personal body chemistry. You know what I mean? It smells great in the bottle, but once it's been sprayed on me for a while it starts to smell a bit like cardboard. I know this isn't the scent's fault, because my old roommate used to wear it and it smelled fine on her.
Luckily, I've had better luck with La Fleur. It maintains it's bottle scent on my skin. As far as the actual scent, it's very similar to the original Viva La Juicy. So similar that I'd say if you're a fan of the original fragrance and have none of the issues I have, you probably don't need to purchase La Fleur.
To me, La Fleur is ever so slightly fresher. Both Viva La Juicy's have that sweet, fruity yet floral scent, but La Fleur seemed to me to have a few more flower petals thrown in the mix.
Looking at the descriptions for both perfumes, though, it seems that the only difference between the 2 is that La Fleur doesn't have the Amber and Pralines that Viva La Juicy has. That annoys me a little bit because it almost seems like Juicy Couture just took their perfume, took out a note or 2, and then slapped a new name on it. It's just not too creative.
Would I be interested in purchasing a full size? Yes
Despite it being almost a carbon copy of the original Viva La Juicy, I can't deny that it does sit on my skin better and seems to be a little more lightweight of fragrance (possibly due to the 2 notes they took out). It still maintains that flirty, fun fragrance that we've all gotten to know so well, just not as heavy (not that original was heavy in the first place).
