I've been asked to do a cake like this in buttercream

. I have been decorating cakes for 15 yrs just not one as detailed. My 1st guess is to use royal for the piping BUT I am worried about breakage during transport. Which would be best? Also, I normally transport tiers separately and assemble on site. This cake looks as if it needs to be assembled due to the design? I can't decorate on site. It will be outdoors etc. Any tips tricks or suggestions would be greatly appreciated. I'm lacking confidence on this project :/ which is totally out of the norm for me!! Thank you in advance!!!

i mean that could be all buttercream and assembled before or after delivery--i think the intracacy of the design is throwing you--it's perfectly doable--

the 'being outdoors' part mean it's likely it will melt if it's hot but...

How much of this is impressed & how much is free hand? I am planning of starting with impressions and over piping adding embelishments along the way. I have blown up the pic to try and get the feel for the style and will try to get as close as possible to the design. My brides main concern was that this reminds her of her style wedding dress, not the exact pattern. Thank you for your comment!!! You are right! I know I can do this just haven't done this much piping in a while..... Really wanting it to be great!
