Help me find this pleaseee

So its a typical historical reincarnation romance. The FL becomes a care taker or mother of the children of the ML.

i remember very little but i remember a plot line where she designed comftorable dresses which became super popular. There where also a lot of these events i think, which because she comes from a modern world she "invents" stuff like the dresses, storybooks and other stuff.

I cant remember a lot but i suddenly really wanted to find this so if you know anything that sounds a little familiar to this PLEASE let me know!

Some parts may be wrong since its a long time since i read it
