perfect
I chose a size Large, which I normally wear in women's underwear. I am 5'4" and 158 lbs. The fit was perfect. They stayed put and didn't ride up. The material is soft. Machine wash and dry well. No complaints to speak of.

Poor quality, easily rips at seams.
Size: Medium, Color: Organic Cotton 5 Black Pack
Fit is great but these things do not hold up. I have some Gap hipsters that are older and they are much higher quality. These rip and tear way too easily.

Elastic band is not great
Size: X-Large, Color: Organic Cotton 5 Black Pack
The cotton material is comfortable and seems like it will last some time because it isn't thin like most. However, I could really use a thicker, more durable elastic band.

Comfortable
Size: Large, Color: Organic Cotton 5 Black Pack
Comfortable and decent looking black underwear in a hipster, boy cut style. Material is soft and lightweight, kind of thin, but since they’re black they’re not see through at all. The elastic band at waist is also thin and not too tight so it’s very comfortable and doesn’t dig in at all. Five identical pairs in the order makes this a decent value, especially at this price and for Organic cotton material. The large size was perfect for me I sized up based on the recommendations). I’m pretty happy with this order.
