They fit perfectly! I have both the medium and the small sizes, and they fit pretty much the same way. I wear the small for cardio workouts and the medium for days when I do Olympic lifting.

The quality is excellent, and the price is good.

My order from this shop arrived quickly in Canada, taking only 14 days from the order date. The items were packaged well and are of high quality. They feel luxurious. I first ordered an XS (I wear a 30C/32B bra) which fits, but is snug; the tag says "2". I then reordered a Small which fits perfectly, the tag says "4". Therefore, if you typically wear a Lulu size 4 bra, the Small should be ideal. I am very happy with my purchase, thank you!
