If you like GIT, you maybe should also try
- Geo F. Trumper Skye: fresh, light, airy, but long-lasting.
- Floris JF: starts quite similar to GIT (or Cool Water), but then it it develops to a very complex, rich fragrance.
D&G is a much warmer, also very well-made fragrance. You could also try
- Frederic Malle's Iris Poudre: a bit less sharp than D&G. It starts quite powdery, but then it becomes muskier and more floral; it's a unisex fragrance, but definitely more on the masculine side. This is really a must-have IMO - a masterpiece!
- YSL M7: a warm, rich and complex fragrance perfect for evening or cool weather.
