Stressing over this baby shower . I haven't started on anything . Except the date .. July 16th . 
Where would you recommend to find a perfect baby shower dress ?  (Also feel free to give any ideas where to get baby shower things? Cakes? Anything !) don't have a set theme so anything would help😊 just look for ideas . btw it's for a BabyGirl!!
