Maternity fashion trend: Polka dots and spots as seen on pregnant Kate Middleton

Kate Middleton showed off her growing baby bump late last week in a gorgeous polka dot maternity dress from Topshop.

The Duchess who was touring the Warner Brother studio teamed up the £38 dress with a black Ralph Lauren blazer and simple black heels.

The dress, which we featured a few months back, sold out within hours of the Duchess showing it off. However, we think she's set a polka dot trend for the maternity world and predict big things for this print.

We've picked out some of our fave bits in preparation for the big trend. Get them now to make sure your up-to-date with future fashion.

Kate Middleton to show off maternity style for later stages of pregnancy at Cruise ship launch in June

Followers of Kate Middleton's maternity style will get another fashion fix, as well as ideas on how to dress their baby bump in the later stages of pregnancy.

According to sources, the Duchess set to christen a cruise liner in Southampton  just one month before her rumoured due date.

The pregnant royal has apparently agreed to become the "Godmother" of the Princess Cruises' new liner, aptly named the Royal Princess, on June 13. 

She will make the most of her new role taking a tour of the new ship, which has an impressive 27 bars and restaurants as well as an entertainment area that seats 280 people.

Impressive as the ship may sound we just can't wait to see what maternity clothes Kate chooses to show off her bump.

Maternity floral fashion for Spring/Summer 2013 and get Kate Middleton's floral frock look

Holly Fulton Spring/Summer 2013

Florals have once again regained their spot in Spring/Summer's must-have lists.

This season the trend sprouted up on the catwalks of Prada, Holly Fulton and Moschino to name a few, channelling both the sixties hippy era as well in a bolder sense with big prints and pop up florals sewn onto tops, skirts and scarves.

And it seems Kate Middleton has been quick to incorporate this trend into her maternity wardrobe. Last week she was spotted scooping up a delicate print floral frock from UK brand Lovestruck.

Although the £37 Deirdre frock wasn't actually labelled as "maternity" the elasticated waist makes it a perfect for that growing bump.

We've picked our fave five floral frocks for this season, including Kate's bargain lovely. See the gallery below for all the fashion.

Peaks of London creates pregnant Kate Middleton maternity wardrobe

The news that Kate Middleton is pregnant has caused a fashion furore, with everyone speculating what the Duchess will be wearing to show off her bump in the coming months.

Peaks of London has joined the club, coming up with a range of gorgeous pieces fit for the princess and of course pregnant women everywhere.

Designed with the Duchess of Cambridge in mind, its Audrey dress is a must-have item for any sartorially conscious mothers-to-be.

Not only will it see you through pregnancy with it’s adjustable waistline but also into breastfeeding.

Additionally the stretchy material of the company's Marilyn dress - which is almost identical to the famous Issa frock Kate wore at her engagement announcement, will ensure it grows with your bump.

We also love the Drape dress, which features an adjustable ribbon that can be loosened or tightened through the stages or pregnancy.

Take a cue from Kate and go for a blue palate, which is tipped to be one of the top colours for this party season and through into SS13.

See some of the company's princess inspired pieces in the gallery below.

Peaks of Londons' Marylin dress is very similar to Kate's Issa engagement dress, making any pregnant and breastfeeding lady feel like a princess.

Pregnant Kate Middleton's maternity wardrobe: Evening dresses which are also great for the Christmas party season

Now that Kate Middleton has announced she's expecting, having a bump is set to become one of the hottest trends of the season.

And we can't wait to see what maternity style she'll be rocking once her bump begins to show.

Until then we've looked at her current wardrobe and matched up some maternity dresses that would slot in perfectly.

Kate's style has always been very classic,  with her love of wrap dresses coming through at a range of occasions. Most notably the blue Issa wrap frock she wore when her engagement to Prince William was announced. Thankfully this silhouette flows perfectly into maternity wear with wrap dresses being a key way to show off your bump.

V-neck frocks as well as lace just below the knee styles are two other staple pieces which can be found in the Duchess' wardrobe, with Kate channelling these looks more than a handful of times on the red carpet and at evening events. Again, this is great for her maternity wardrobe with these styles also flattering bumps

A colour palate of blues, silvers and black may also prevail in Kate's maternity wardrobe.

With this in mind we've hunted around the virtual highstreet to come up with a range of maternity evening dress styles Kate may go for.

Buy them now and get ahead of the Royal maternity fashion game,  as with Kate's love of highstreet items we think some of these may be flying off the virtual shelves.
