Libby Castravet (née Potthast) is one 90 Day Fiancé star who boosted her confidence when she slimmed down, and her post-weight loss outfits of the day are getting attention. Unlike some of her fellow franchise cast members, Libby did not want to shed a lot of pounds. However, the 90 Day Fiancé franchise regular has shown off some cute looks after bouncing back between pregnancies. This led to Libby revealing new fashion looks on Instagram.

Although Libby and her chaotic Potthast relatives get criticism from fans, the American mother is one-half of a successful franchise couple. Libby and her husband Andrei revealed that they had a stable marriage on 90 Day Fiancé: Happily Ever After? season 6. The two are regularly called bratty and entitled by viewers. However, they are a compatible duo who have a thriving (and surprisingly normal) marriage. Libby and Andrei share a young daughter named Ellie, and Libby is currently expecting her second child with her husband.

Between pregnancies, Libby has jumped on the trend of promoting weight loss products to her followers. Many 90 Day Fiancé fans called out Libby for revealing before and after photos that did not feature a noticeable change in weight. However, losing a small amount of weight appeared to give Libby confidence. This led to the American woman proudly showing off on social media, as she revealed her leaner frame and experimented with different looks.

Libby Bares All

Libby decided to dress up for an episode of 90 Day: Bares All last September. The mother chose an autumnal orange dress that hugged her body and showed off her slim waist. Libby accessorized with glowing bronzer and colorful heels. While Libby appeared slim and pretty in her images, some fans called her out for always seeming like she's holding her breath while she is posing. Many 90 Day Fiancé fans would prefer to see the Potthast sisters looking more natural (and less uncomfortable) in photos.

Libby's Formal Wear

Libby appeared more confident and comfortable during a formal outing with Andrei last December. She chose a gorgeous teal dress that tied at the waist and revealed her slimmer frame. She also opted for full glam when it came to her hair and makeup. Libby’s formal attire earned her much praise from her fans. Meanwhile, Andrei posed by his wife's side in a colorful button-down shirt.

Libby's Date Night

Libby prefers to wear glamorous dresses for outings, as she showed in this date night photo with Andrei. It was shared at the beginning of March. The image was posted two weeks before Libby announced her pregnancy to 90 Day Fiancé fans, which means that she was already pregnant at the time. However, Libby was not showing, as she appeared slim and elegant in a pale blue dress and turquoise heels.
