Can you help me with my body type?

Bust: 32 inches / 81 cm (I'm a 65C in EU - it's a 30B in US and a 30C in UK)
Under the bust: 28.2 inches / 72 cm
Waist: 24.7 inches / 63 cm
Hips: 35.5 inches / 90 cm

When I try the body type calculator ( http://www.calculator.net/body.....lator.html ) it tells me that I'm a pear, spoon or bell. When I put on weight it's on my bottom - and my waist follows (my waist-hip-ratio is around 0.68 - 0.70).

I'm (very) underweight and some years ago (when I was 15 years old) I was 32.3 inches / 82 cm around the bust, 23.5 inches / 60 cm around the waist and 33.5 / 85 cm around the hips. Today I'm 19 years old (almost 20).
