I like the idea of a cat outfit, I know there was one before but it was pink which isn't for me. Also I love adding cat ears to maids outfits (or wearing in town tbh). I think I've noticed a few other members say they buy fancy cat ears to wear, I've seen a few on ebay which look lovely and are a lot nicer than the standard ones.
Belly dancer look/ harem girl, I like these looks espically in blues and dark purples. Also if you manage to get some body chains in stock these will work well together (might just be me but I love adding my own personal touch to outfits like earring etc).
I like the wench and gypsy look, some maybe an idea to expand here. I also like corset style belts which would help with this look and also will be a great item to go with many outfits, lingerie, and day/ night wear.
Miliary officer both male and female outfits. \Military style dresses look so much better than the camo green outfits, a lot more sexier, and work well with a trench coat and crop.
A burlesque ruffle back/ feather skirt would be nice and would work well for the cowboy bar scene. Though a complete outfit would work well for people who didn't want to piece bits together.
A toy stethoscope might be good as well, though personally I went for a real working one, but a cheap one to go a longside some of the nurse outfits would be nice. Also it would men guys could use it to play doctor too.
I like the cheer leader look, even though at the same time I feel it's tacky. Cheer pompoms would be nice even if not an outfit as they would add to burlesque.
Also I've seen something like this before but can't remeber where, but a ruler style crop. It's a lot safer than the standar ones you can actually buy from shops and less likely to break. I really like the teacher look but all the rulers I own won't work for this whether they are plastic, wooden, or steel.
I also like the sexy Geshia look, though I understand it may not be in the fashion season right now. But currently I would love to be lazying about in a kimono style outfit due to this heat.
With outfits I tend to like the more stylish ones. I really like the bluebella maid outfit for example, it looks like it's good quality and is sexy but doesn't expose too much. I feel some that expose too much at the time can be overly distracting when performing role plays.
I also like good quality outfits as I like wearing them out. Though I understand I do this more than most people as I have been know to wear an outfit out to just go shopping in.... people never forget a sober girl dressed in a pvc nurses outfit even after years.... but basically quality is key.
I'm sure there's a few more I will think of. I really do love my outfits, and I know I suggested a lot of props but when you have gotten an outfit in a certain genre and are happy with it you are unlikely to replace it so adding to it is nice.
