Lululemon tiffany blue mint set co-ord

The set of crop top (size 10), duck down vest (size 10), leggings for someone who wears size 6-10 I put the size as 8 because I think Lulu is a little on the smaller side, so this set will work for someone who is 10 but also for someone who is 8 or 6 (will fit slightly oversize)
