The following fold settings will do it:

"---------------------------------------------------------------------
setl foldmethod=expr
setl foldexpr=FoldexprIndentedOutline(v:lnum)
func! FoldexprIndentedOutline(lnum)
let lev = indent(a:lnum) / &sw + 1
let levn = indent(a:lnum+1) / &sw + 1
return levn>lev ? '>'.lev : lev-1
endfunc
setl foldtext=FoldtextIndentedOutline()
func! FoldtextIndentedOutline()
return substitute(getline(v:foldstart), '\t', repeat(' ',&sw), 'g')
endfunc
"---------------------------------------------------------------------

The substitute() in 'foldtext' is needed when indenting is done with
tabs. Otherwise it can be simply
:setl fdt=getline(v:foldstart)

To also display level and/or the number of hidden lines, append
something like the following to the foldtext string:
.' /'.v:foldlevel.'...'.(v:foldend-v:foldstart)
