I don't know about you, but I like my milk chocolate to be brown, not beige -.-"
Nonetheless, this is such a pretty colour. It required two coats for opacity, applied with a little bit of difficulty (as I seem to have with most light coloured cream polishes) and wasn't a particularly fast drier. The picture below is the best representation of colour, which is a pinkish beige cream. Nice neutral work-friendly colour!
Milk Chocolate is slightly (very slightly) more pink than Beige Style, but other than that the colour and formula are pretty much a dupe. BUT, the major difference is the brush. Rimmel have decided that fatter brushes are better than regular brushes... I personally cannot use fat brushes, I end up with clumpy uneven application. I guess it is really just personal preference, or maybe I'm just not skilled enough. I've tried the Beige Style, and I had to even it out with a really thick coat of Seche Vite.
Description from Rimmel's website for the Lycra PRO:
NEW! The 1st professional nail polish from RIMMEL Professional finish effortlessly! “Ultimate” Maxi brush for an ultimate mistake-free application. The inimitable combination of the superior formula with Lycra® technology + Maxi brush innovation guarantees perfect coverage for superior shine & wear.
So, though they come in pretty colours I will not be purchasing any more of Rimmel's new Lycra PRO polishes because of the Maxi brush.
