Speaking from my personal observations and general understanding of fashion, it's best not to wear high heeled shoes, be them wedges or 'stiletto' type shoes.

They do add a certain flair to the way you walk, make your legs look longer, etc. The last part may be irrelevant for those wearing jilbab, but the way you walk isn't really concealed.

As for "wanting to look good outside"... you're not supposed to look good outside. Not saying you should look like a hag - of course, you must look presentable and be neat and clean - but what's the point in wearing high heeled/platform shoes to 'feel and look good'? For who, exactly? You can feel and look good in the comfort of your own home safe from any prying eyes.
