Where is the use of having a lot of dresses when she isn't out yet?
There's no need of sending home, Daisy, even if you had a dozen, for I've got a sweet blue silk laid away, which I've outgrown, and you shall wear it to please me, won't you, dear ?" "You are very kind, but I don't mind my old dress if you don't, it does well enough for a little girl like me," said Meg.
"Now do let me please myself by dressing you up in style.

I admire to do it, and you'd be a regular little beauty with a touch here and there.

I shan't let anyone see you till you are done, and then we'll burst upon them like Cinderella and her godmother going to the ball," said Belle in her persuasive tone.
Meg couldn't refuse the offer so kindly made, for a desire to see if she would be 'a little beauty' after touching up caused her to accept and forget all her former uncomfortable feelings toward the Moffats.
On the Thursday evening, Belle shut herself up with her maid, and between them they turned Meg into a fine lady.

They crimped and curled her hair, they polished her neck and arms with some fragrant powder, touched her lips with coralline salve to make them redder, and Hortense would have added 'a soupcon of rouge', if Meg had not rebelled.

They laced her into a sky-blue dress, which was so tight she could hardly breathe and so low in the neck that modest Meg blushed at herself in the mirror.
