...is upon us! And this is both an exciting and agonising time for me, lol.
Innocent World kick-started it with their Lucky Packs and Metamophose is having their Summer Lucky Packs as well, which starts today. A quick check says the Meta LPs aren't available yet. So keep checking if you've been wanting to get one!

For larger size girls who are worried about whether the items in the LPs would fit, I would recommend getting the 10,000yen LP as the skirt included in the pack would have, in all likelihood, a stretchable waistband. I've bought both the 10,000 and 15,000yen Meta LPs early this year and while the jsk in the 15,000yen pack did fit me, it was a tight fit and I didn't feel or look comfortable in it.
But the Summer 15,000yen LP from Meta does have an example of a fully-shirred jsk listed so there's always the possiblity of getting one such item...but that's the fun about getting a LP! Part of the enjoyment is the anticipation of not knowing and hoping, heh.
Just a note that Meta would likely be having their summer online sales after the LPs. So if you prefer actually knowing what you're getting, take a chance and wait for the sale to start instead.
