Largest size of this particular blouse. Official measurements aren't listed on the bodyline site, but I would say this would fit someone with a bust up to 105cm, and around 100 waist. I'm 111cm bust and 100cm waist, and my boobs were just slightly too powerful. 

No shirring, but has a nice shape on as can be seen in the promo photos 

UK shipping £6. Shipping subject to all sorts of hell, including postal strikes, holiday and covid delays
