The 45-year-old actress kicked off her Ghostbusters tour last month, as she and her co-stars appeared on Jimmy Kimmel Live for the show's special game night episode on June 8.

The Ghostbusters star made her way to London several days later on June 17, where she promoted her new movie at BBC Radio 2, rocking attire from her upcoming holiday collection. The actress paired a patterned tea length skirt with a pink blouse and matching sandals to complete the feminine look.

After taking a little break from the festivities, McCarthy stunned at the Ghostbusters premiere in Los Angeles on June 9 -- the actress sported an on-trend yellow number, wearing a 1950s-inspired custom creation with lacy floral embroidery. "It's an elegant version of new and old Hollywood," McCarthy's stylist, Judy B. Schwartz, told Pret-a-Reporter on the summery ensemble. "And the takeaway from that [premiere] look for any woman is not to be afraid to experiment and to always keep your look evolving."
