I got this and wore it to wedding last week, absolutely love it and it's so flattering. I don't normally like new look but this has more of a high quality look and feel to it. They have different ones on the website too.
I love LindyBop and they're always my first port of call for an outfit when an "occasion" comes along in the social calender.
I love their quirky patterns and have many daily wear dresses and skirts as well as "occasion" outfits - I have this cupcake print skirt that never fails to get compliments when I wear it and recently I wore this Alice in Wonderland inspired dress with thick tights and chunky heel boots to a couple of family christenings and everyone loved it!
Also, one of the best things about their dresses and skirts is that most of them have side seam pockets, which really shouldn't make me so excited but I am so sick of skirts and dresses with no pockets to speak of!
You should try it! I actually bought the Alice in Wonderland dress because it was a nice print but wasn't too in your face, and you can either dress it up or dress it down. I wore it to one event with heels and clutch bag and another with thick tights, cardigan and boots and it looked good worn both ways.
It can be scary to try new things (and some of their prints are even too bold and in your face for me) but there's no better time to try a slightly quirky outfit than an event that people are going to be looking at you anyway. If someone is going to make a comment about your outfit, might as well give them something to comment on!
Church in December might be cold so something with sleeves and something that can go nicely under a coat? Also needs to be comfortable as you will be carrying baby at some point. Pockets would be a bonus for tissues to wipe up drool/baby sick?
