I'd say Alegra is Gilda's sister... but the cooler, sassier sister who packs a punch. This pink is super glittery and vibrant!
And for comparison's sake here's Alegra against OPI's The One That Got Away (Katy Perry Collection). The only real difference between the two is that The One That Got Away is blue-based while Alegra is red based. They're pretty much the same externally besides that. So I guess the main thing is to decide which looks better on your skin--blue-based tones or red-based tones?
