6 inch huh? Well あなた know what? あなた can wear whatever the hell ya want! ;)
Grey isn't really a "standout" color, so anything look's great! For me I"m a スカート kind of girl so try a mini または a high waistline so It show's of your body figure along with あなた legs. Perfect combo!~
または if skirt's aren't really your thing then there are other options. If it's pretty hot where あなた are (lucky >.<) then go for short shorts! Some are so short that they Hug your body so if あなた ever pick that kind those then that does a FANTASTIC thing to your body. So もっと見る people look st your legs and eventually your shoes. :)
If your not feeling in the "Multiple clothing" mood then あなた can still make a dress look great too! Long, short, anything can work!
For top's well あなた can pair really anything with a pair of shoes actually. Bright color's are best too. Blue (Dark especially) would look AMAZING with your shoes. Tank tops, over sized (adorable) sweaters, even regular T-Shirts would make your shoes fabulous.
It's all about experimenting. What ever あなた like with your shoes work! It doesn't need to Match a specific style, that's why a lot of people follow their own style. So whatever あなた find "cute" in your closet can work with these shoes. I hope I helped! :)
almost anything..since gray is a neutral. ピンク looks amazing paired with grey, and white and black of course, so does green and blue and red...almost any color.
Skirts and dresses not so short... Some kind of pants. Almost any color goes with gray. I wouldn't wear anything too casual with 6 inch heels. I guess they're cool for wearing at night.
あなた can legitimately wear whatever your ハート, 心 desires girl youre wearing killer 6 inch heels bc youre fucking fabulous and no one can tell あなた otherwise. okay? dont dress based on what gets あなた the D または the V. no one gives a shit. so if あなた decide あなた wanna rock those heels while wearing a coconut bra and 草 skirt, あなた can goddamn do that. literally never listen to the shit people say. got it? u go babe <3 <3 <3
