As simple as this may look lol , how would one go about trying to replicate this vertically  combed buttercream look?  Also do you think the dress is made using buttercream and a piping tip?

Evidently your picture or attachment did not come through???

Omg lol let me try again 

That’ almost looks like it’s piping done w/a very small round  tip 

on the cake itself, on the blue part -- you could get that look with a cake comb or even a fork -- just keep brushing it up and cleaning off the comb or fork -- but not too clean -- then the skirt could be done with a wide flat rose tube 

Yes K8 I also thought the same thing   Looking at the right side of the top tier especially  I noticed what looks like  “crumbs” on the lines   One wouldn’t get that w/piping    But I *never* would be able to make such straight lines even w/Using a comb:)   Also the top edges are soooo clean— no sign of having pulled a comb up through b’cream

I think the dress is fondant & it sure is well done  

I think its fondant too! And who made it did a great  job

I didn’t think about using a fork but I did think about Using a comb! Should it be done on freshly iced cake or on crusted bc?

I would practice on both   Find what works best for you   I’m thinking fresh  might be best but those tiny knobs /crumbs make  me think crusted 

ok -- put it this way I could do all of that in buttercream   

it says it's buttercream here:

Ok, here's my two cents....the vertical lines appear to me to have been done with something small and rounded, like the end of an artist paint brush or a small ball tool, maybe even a couple of sizes ball tool.  It would be necessary to use a bench scraper or something similar as a guide to insure straight lines.  Honestly, I can't tell if the skirt is buttercream or fondant.  I sure as heck couldn't do it in buttercream!

How  would you go about creating the skirt? ...i was thinking maybe a buttercream transfer but.idk lol

sweetdreamzz, the skirt appears to be made of fondant, applied in strips and shaped for movement.

I sent a picture of the cake, that sweetdreamzz posted, to melissa on mycakeschool dot com  because I found a very similar cake in a tutorial she has on there -- this is what she said:

Thanks, Kate!  That is some sweet piping!  I am totally in awe of all of you who do magic with a piping bag!

For the combed buttercream look, you can also use a straight edge like a bench scraper and just push it into the buttercream. Time consuming, but it looks cool. I've done it that way and also with just a palette knife that has a pointed end to it.

Omg Thank you ladies ! That awesome. I too tried to recreate  this cake using buttercream. The colors were requested to be changed to rose gold and champagne . They requested rhinestones for the too if the dress and I couldn't find any so I made candy and broke it up for the top.

good call on the crushed candy — nice work  

Thank-you !! 

I agree, the crushed candy was a brilliant idea, far superior to rhinestones!  Beautiful cake and you nailed the colors.

Thankyou! I love this group and how much support and encouragement it provides.
