This Meta blouse is secondhand. I have never worn it but did wash it when it arrived. Missing a 1 or 2 of the removal chest ribbons, but it has one. 
Blouse is plus size friendly as it has back shirring.  Sleeves have elastic in them , it is not uncomfortable, tight elastic.
I am a size L/XL in Target sizes and I can button this blouse up while wearing a sports bra...if that gives you an idea

I am leaving sweet style so this blouse needs a new home!

This is the most similar Meta blouse I could find on Lolibrary - https://lolibrary.org/items/meta-dot-frill-short-sleeve-blouse that is where I got the measurements below from

Bust

95cm

Length

49.3cm + frill 3cm

Waist

81cm

Shoulder Width

35cm

Sleeve Length

20cm + frill 3cm

Comes from smoke free and pet free home.
Shipping can be priority mail BUT If I can fold it up real tight I might be able to get it in a regular envelope.
So the average for US would be $5 at the cheapest and priority mail is about 9.45 with insurance included.

I will ship within 3-4 business days
