chanel vs butter

i'm obsessed with butter london's nail colors - they're literally all i wear (right now i'm wearing yummy mummy, a gorgeous beige that flatters every skin shade out there and has been sold out on the butter london site for months - snagged it at ricky's in soho the other day) - but the new chanel colors.. DIE rachel zoe style. i'm thinking the "steel" might be too similar to my butter london "chimney sweep" - but the "strong" is just too good to pass up. especially since they'll premier at the soho chanel in a week or so...and i work three blocks away...
