Kate Middleton's baby bump is becoming more visible. However, as the Duchess of Cambridge continues with her public appearances, she reportedly also manages to conceal the bulge with the clothes she wears. Her clothes reportedly also give a hint on the gender of her second baby.

According to Inquisitr, Kate Middleton had no problem concealing her growing baby bump when she and Prince William visited the Valero Pembroke Refinery on Saturday, Nov. 8. Straight from their "babymoon" in Scotland, the Duchess and Duke of Cambridge headed straight to Wales to attend to another royal duty. Kate was seen wearing a long blue-coloured wool coat that reportedly successfully hid her pregnant belly. Kate looked lovely as usual; however, her choice of clothes, especially its colour, is said to be a mother's instinct.

There have been many speculations on the gender of Kate Middleton's second baby. Many wonder if she is carrying a baby girl or boy. According to Inquisitr, the Duchess of Cambridge has been wearing anything blue since her second pregnancy was announced on Sept. 8. The International Business Times once noted Kate Middleton's blue thigh-slit dress that she wore on Oct. 21. That was the first time the Duchess returned to public appearances since the announcement of her second pregnancy.

Her choice of blue-coloured dresses for her wardrobe supposedly indicates the gender of her second baby. Wearing the colour reportedly hints the Duchess is again pregnant with a baby boy. However, per Inquisitr, Kate Middleton favours the colour blue in general. She has reportedly been taken with the colour ever since Prince William gave her Princess Diana's sapphire ring.

While fans cannot wait to find out the gender of Kate Middleton's second baby, Inquisitr claims the royal couple is being patient. Sources have supposedly claimed that the Duchess and Duke of Cambridge want to be surprised when the time comes for them to know their baby's gender. Despite all the baby boy speculations, Prince Charles, on the other hand, prefers a baby girl. BBC quoted the future monarch on his preference for a granddaughter. "I'm looking forward to it - but I hope it will be a girl this time," he said.
