Throughout her pregnancy, Ashley Darby has been making sure Baby D gets plenty of vitamin D, no matter where she is. This past sunny Memorial Day weekend proved no different for The Real Housewives of Potomac mom-to-be. 

Ashley took advantage of the warm temps and headed to Bethany Beach, Delaware. Adding to her collection of fabulous maternity swim moments, Ashley broke out a multicolored strapless bikini to bask in the warm weather. The RHOP stunner was positively glowing while celebrating the national holiday oceanside. 

Just look at that glistening bump! 

Ashley also took a moment to commemorate Memorial Day. "I am incredibly thankful to be born in a country that allows me to read, question, discuss and evolve. By no means is the USA completely just, we still have a long way to go, but there are countless men and women who have sacrificed their lives to ensure we maintain the ability to grow as a nation. This holiday isn't lost on me and it won't be lost on Baby D either," she wrote.
