PRETTYGARDENWomen's Tie Dye Two Piece Pajamas Set Casual Long Sleeve Sweatshirt with Long Pants Loungewear

Are they true to size? Will it be too big or too small?

How do you wash? Mine says dry clean- but is it safe to put in the washer?

Can you make extra small (xs or even xxs) in the two piece pajamas set long sleeve sweatshirt with long pants sleepwear??? small is very baggy/large.

Can I find out about the bag in the picture? Thanks
