Yes, if you are sure to get the proper size they fit beautifully....I have had Leroy's for three years now and there is not a thing wrong with it and the velcro is still super strong....
If the suit does not fit close to the body then it is not the proper fit...if they are able to pull their feet up into the suit once it is on then it is to big. Do not take your bird outside with it on if it fits like that.
The reason I go with Wanda's Critters is because her customer service is excellent and when I find that, I let everyone know...also, she has such cute suits...
Oh, I almost forgot....if you look at the pic of my babies in their suits...you will see that Leroy's tux fits snug to his body and Dusty's has a gap in his suit...I had to take his suit in a little and shorten the straps....I also love that they have the little diapers in them so you don't have to worry about getting pooped on...that is always a BONUS!!!!
