Was only missing the white and yellow wet suit, which I purchased and put into My Wardrobe. The achievement still says they are NOT in wardrobe even though I've refreshed a couple of times. Any ideas???

Did you go to your wardrobe after putting them in?

the new achievements activate on clicking the 'items required' in the achievement page!

and ...thanks guys. Yes, I tried both of those ideas, but when I opened 'items required' it still said I didn't have either item in Wardrobe. I gave it until this afternoon and looks like it straightened itself out. Just another glitch on the Achievement Road (lol). :)
