Invitation etiquette

I thought it was a little odd that G and I were invited to a distant cousin's wedding on my mom's invitation, but I figured that they didn't know our address and just decided to combine us on my mom's invite. Wrong. I just found out today that my cousin and her husband, who have been married for 19 years, were not sent an invitation, but instead, included on her parent's invitation. Another cousin of mine, who has been married his wife for five years was invited on him mom's invitation as well. After living and breathing wedding etiquette for six months before my own wedding, I know this is definitely not the correct way to invite people. Now I am a bit scared about attending the wedding if they have already cheaped out on the invitations.

I guess I need to buy a dress also, because I have worn most of my dresses in front of my family and it is a faux pas to wear the same dress twice. I hate wearing dresses because they make me feel fat and frumpy. Argh! Maybe dress shopping will help motivate me back onto my treadmill.
