These are nice, fit is good and underwear is comfortable. I would buy these again. Maybe I thought they would have been made of heavier cotton, but they are suitable for me.
I usually love Fruit of the Loom thongs. I wear a size 7. They normally aren't flimsy and wear really well. These were flimsy and didn't even fit the same! I was very disappointed.
Fruit of the Loom has their own sizing which does not match standard dress sizes and the conversion size chart, on the package, is not listed anywhere on the product description page. I ordered a size 8, thinking it is a dress size 8, but in Fruit of the Loom sizes, size 8 is a Xtra Large. Inquire about the sizes or look them up before ordering.
This is a nice gift for your girlfriend, they look so nice and comfortable, and also, nice colors :)
