I tried this on in store as I had my eye on the red one for a while. The dress looks beautiful, especially on the model, but it's not what it really seems. The dress actually runs large, but the straps themselves are true to size. I tried on L, which fit well, but I had a hard time getting my arms through and adjusting the straps properly. Even after I did, the straps sat too high up my body, almost making it look like a halter instead of a proper cowl neck backless dress with criss cross straps
