Shopping online is great because you can do it from the comfort of your own home – and don’t have to waddle from store to store looking for the perfect baby shower dress! What is the trick to finding clothes that fit when ordering online? Most sites have a fit guide that allows you to order clothes according to your pre-pregnancy size, as well as measurements for chest and hips. Check out A Pea in the Pod’s size chart here >>

Pregnancy cleavage can be a perk, however I have heard many pregnant moms-to-be complain that many maternity tops are too low cut and leave them feeling self conscious. One easy solution is to layer a lightweight cami underneath the shirt to give your coverage – not to mention the layered look is a chic look this season.

Look for maternity clothes that will grow with your changing body. Jeans should have a belly panel or buttons on the side that can be adjusted. Tops should be cut long enough to cover your baby bump from trimester one to trimester three. Look for dresses that have tie backs to give your body shape and definition throughout your pregnancy. You can also pair your own belt with tunic tops and flowing dresses under your baby bump for a chic look.

What can you expect in her new maternity line? “Full of breezy, everyday pieces, the collection is aimed at the modern mom-to-be who wants to maintain her fashion edge throughout her pregnancy,” the press release reveals. “The collection has a vintage ’70s feel.

Lovely in layers: During pregnancy, your hormones are going crazy which means you are hot one minute, and maybe feel a little chilled the next minute. Layer a lightweight cardigan over a tank top or short-sleeve tee so you feel comfortable no matter what mood your body is in.

Buy new underwear: You would be surprised how tight underwear can put you in a bad mood. As your belly (and your body, in general) grows and changes, pick up some new maternity underwear. Get tips on buying maternity underwear here >>

And why you are at it…

Buy a new bra: Most women will find their breast size increases by at least one cup size during pregnancy. As soon as your pre-pregnancy bra starts feeling tight, get measured for a new bra that is comfortable and supportive of your new pregnancy cleavage.

Ditch the uncomfortable clothes: Even if those designer maternity jeans look fab, if they don’t feel fab then don’t wear them. I know I couldn’t wear jeans at all in my third trimester. If you don’t feel good, you won’t look good.

Stock up on dresses: Whether you prefer long maxi dresses or flirty sundresses, a chic dress is not only flattering on your pregnancy curves, but comfortable as well. You don’t have to mess with matching a top or a bottom and they can be dressed up or down.

The first step in getting poolside chic is to find a suit that flatters your body type and one you feel comfortable in. A bikini is great for moms who want to show off their bump, while a full-piece suit is perfect for looking classic and polished. For those pregnant moms-to-be who want to show a little more skin than a full –piece, but not as much skin as a bikini, then the tankini is the perfect option. Pictured is the Striped Maternity Tankini from Motherhood Maternity.

She suggests wearing wrap dresses and maxi dresses to pull this look off. “One piece Maxi dresses that have paisley or floral prints are best, as they not only help cover and flatter that baby bump (and it’s so easy to wear), but they further dial up that beautifully ethereal look of the mom-to-be,” she says.
