Our wedding is scheduled for 5 months after I deliver our first baby and I'd love suggestions on the right kind of dress to look for.
I'm a small person to begin with. Started the pregnancy at 125lbs, and looks like I'll not gain more than 30lbs (I'm 6 months pregnant now.)
I'm 5'3" with 32E breasts to begin with so I'm worried about what styles will suit post-baby boobs.

My fiance loves the spaghetti strap sheath dress look -- thought on whether theres a chance in hell I'll be able to pull it off with the proper undergarments?
Thanks!
Heather
Re: Sheath Dresses for 5mo post-partum?
If you haven’t “popped” yet, go try on some dresses. It will give you an idea of how wedding dresses are constructed and will help you make a decision on weather you would feel comfortable in a sheath or not.
The other thing is, you won't know how YOUR body responds until after you've had the little one. I've seen individuals who are back to their pre-baby weight in weeks, and others who never see that ever again. Some whose chest shrinks and some who go up a massive number of sizes. Know that you will not go without a dress on your wedding day and you may need to purchase off the rack, but that's really NBD! Do not turn the purchase into an emotional sale, do not "settle" because a shop guilt trips you into thinking you won't have a dress because of shopping close to your wedding, it's a business transaction, and the goal is for you to look in the mirror in awe of how awesome you look and feel (especially in those first months PP when life with baby starts to kick in!). Your FI may have an idea of what he likes, but the dress is about you and your choice of YOU what to look like on your wedding day that makes you feel like a million bucks (while staying within or below your budget - which we always tell brides to plan half of your dress budget for things like undergarments/crinoline, shoes, headpiece/veil -which will save tons if you DIY or purchase online, and the biggest expense of all, alterations.. So when the shop asks "what is your budget" we suggest half for this reason because if you tell the shop $1400 they're going to start with showing you $1399.99 dresses for example instead of $700-800..)
And make sure you can nurse in the thing if you BF.
Honestly, I have to agree with starmoon. I think you should wear what you feel beautiful in, but I honestly can't think of a less flattering style on a newly postpartum body than a spaghetti strap sheath dress. You can certainly look into various undergarments and strapless bras, but personally no way would I want to do spaghetti straps with E cups or bigger.
