I have a straight figure.
What features should I be keeping in mind when clothing?
Which dresses should I choose when dressing asian/indian/western?

A more important aspect you didn't mention... is what type of event you are dressing tor.

There are vast differences between attening a ritzy event, from going to work... or going out with friends.

Anywhere... when going out... what should I keep in mind when dressing up?
If u still need the event; to work,going to college,going out for shopping,on a date,to a relative's place,hang out with friends...

Focus on the things you like about yourself . If it's your lips wear awesome lipstick. If you have nice legs show them off in a classy way. If you have a nice chest show a little cleavage. A rule of thumb is if your showing legs don't show much cleavage & if your showing cleavage don't show too much legs. The type of event is important to know as we'll. Also, know what Colors look best with your skine tone,hair & eyes. If you don't feel fabulous in the outfit you choose don't get it! Bring a honest friend or relative along for advice if possible.

I look good with low necks but better with a fitted top :p
Plus I'm a little uneasy with showing off my cleavage...
Any help?
