The saw a picture of this dress from BoA Design shop a while ago and I did go over to check it out at that time but I thought it wasn’t a group gift and didn’t come in my fit so I ignored it and it turns out I was wrong as it is a group gift and it does come in my fav fit (as well as others).
The group does cost but only a token 10Lds and for that, you get this deceptively simple dress. It’s a one-piece as the belt and that cardigan/upper arm wrap are linked. I did try to take a picture of my arms akimbo so you could see how the texture doesn’t get that stretched look but it wasn’t a very good picture so you will just have to take my word for it.
There are other BoA gifts as well as gifts for both free/cheap groups and some lucky boards.
