The large bright feathers and curly cues on the headpiece look good. Bikini tops rather than real bras are not my choice though. The light blue frontline section with the cage bra is certainly Rio styled. The backpack, which looks very heavy for the model, is outstanding. 
There's a lot going on with the bright blue costume, maybe too much. Could be all the body paint, makeup, face jewels, feather eyelashes and big jewelery though. Sometimes at launches too many accessories can work against a costume. It's certainly vibrant enough on it's own. 
The bra on the red costume looks sturdier to me, & I was instantly drawn to the way it's simply, yet stylishly decorated. 
What I noticed was that adjustments can be made on the waistbands for the red section and the white section. IMO, more can be added, fill them in more, as what you mainly see are the bikini bottoms, and it looks best when you see very little. What makes a spectacular costume is the illusion created that there's no bikini bottom.
If you're a tad more modest and want more coverage, there's always the the c-thong.
So what do you think, is Caribana ready for the c-thong? Bodacious Brazilian bodies can carry off such nearly nude displays, but for the rest of us who weren't blessed with such generous genes, no worries, Rio isn't all about nudity. There's such a wide range of Rio Carnaval costumes with many bands going the traditional route and covering masqueraders in spectacular animal or unworldly creations.

While not visually attractive to the spectators watching the parade, I can see the importance of it now, after experiencing for the last few years how much worse it's getting, all these people jumping in with the parade. Carnival Nationz introduced a team of security pulling ropes to keep stormers out (like Trinidad Carnival bands) also in 2007. That annoyed me, because they were also asking masqueraders from other bands to stay out. However, if security using ropes kept the stormers out, ultimately that's good for the CN masquerader. So I expected to see it when we played with them last year (particularly since their prices went up) - but no. I was frustrated with the lack of security. Stormers eventually infiltrated the band. We couldn't help but notice how much the Toronto Revellers masqueraders were enjoying their mas, the vibe in the band seemed true & free - and no wonder, they were free of stormers.
