Which version of Umbraco are you using? If you're using a version that supports Razor scripts then you could create one and do something like this:
@inherits umbraco.MacroEngines.DynamicNodeContext
@using umbraco;
@using umbraco.MacroEngines;
@{
var node = Library.NodeById(identifierOfFashionNode);
foreach (var child in node.Children) {
// do something with the children of the fashion category
}
}
Actual implementation may vary depending on your version, this is suitable precisely for 4.7.2.
