Engagements are supposed to be surprised only ! Why take someone to get an engagement ring ...then it's no surprise? Is this typical or unusual? What's your experience?

I had 3 people ruin a surprise bridal shower for me although my mom who is planning the party doesnt know that. All she came up with was an idea for a work event for her job that i got invited too. Anyways what should I wear to my own bridal shower? I was planning on getting a haircut early in the morning at the mall and maybe picking up a new outfit. My mom told me we dont have to be at this "work event" until 3:30pm so i have the morning or basically until 1pm free. Please no dumb answers like "wear clothes" :/

We went to the beach today and fished a bit. He did, I just held the basket and helped him. As we came back to the shore I noticed that my nipples were visible through the fabric (I wore a blue one piece). He looked at my chest for a bit, as I blushed and lowered my gaze he looked away too pretending not to be nervous. Why did he act like that?
