I'm 5'6" tall but short waisted with longish legs, I'm not huge but a festively plump 14-16

My main problem is I have a big bust and nothing ever fits right, I have smallish shoulders but am a 36g bra.

Any ideas on what to wear so I don't always look like a boob monster in photos

Are you my sister?!

She has trouble finding clothes which fit her boobs but don't hang off her size 14 body. Recently she's been wearing tunic dresses with tights and heels (very 'mod'). She also wears peasant style tops which expand to fit the bust, but are then gathered around the waist so she doesn't end up with a mass of loose t-shirt hanging off her balcony of a bust. It is difficult for her to find clothes which fit her as she too looks like a boob monster - but she did go to see a personal shopper in a department store and ask them to pick out a few styles which suited her, so perhaps you should try that?

Pepperberry cater for large busted ladies. http://www.bravissimo.com/pepperberry/.
There styles can be a bit hit and miss at times but you do find some gems, I found a dress last year and a couple of tops and they are doing some shirts in the Autumn which look nice. I find fitted tops work best as they don't cause me to have that pregnant look and if you go for something that stretches you may not have to go up a size to accomodate your boobs. Baggy tops make you look bigger all over so are best avoided, a deep v-neck works better than a square neckline. I actually have a small back (32) but have large boobs so I find it frustrating shopping at times and I have quite a slim bottom half and legs so I look top heavy at times as well.

Thanks Eluf and Ellie!

I like tunic dresses but I wish I could wear heels without walking like I'm drunk Maybe some wedges would be as good?

The pepperberry site is really useful, just to give an idea of what goes with what, if you know what i mean. According to them, my shape is "shaped". They're a bit expensive though,but I've got an idea of what to look for, thanks

Things to avoid for big busts:

-high necks
