Why We Like The Spacedye Under Lock And Key Dres

Beyond Yoga serves up the classy, dressed-up version of Spacedye with the Spacedye Under Lock And Key Dres. It offers full coverage with a high front neckline and a built-in bra, and it keeps us cool no matter how hot the day gets.

The dress is it!

What a cute and flattering dress. The skirt flares out a little. I usually wear size small in BY crop top (big lats, shoulders, and pecs), but got the dress in xs because I am short and petite. Don’t want to swim in the fabric. And it’s just perfect! I might hem the skirt up a little (I’m 5’2”) but still unsure. I hope they won’t discontinue this dress, and make more colors. I love it.

So comfortable!

This dress is very flattering, super soft and stretchy and is relaxed in the right spots. Easily dressed up or down, a staple for summer.

This may be one of my favorite designs of all time. TTS 5'5" 108# 32C - bought in XS. Own in 3 colors. It is extremely versatile, comfortable, and classy. Some BY tops are too tight in the bra band for me, but I don't even notice the band on this one. Love the icon, but this is BY's flagship piece IMO. It is THE BEST.

Best day dress.

Love everything about this dress. Cannot wait to wear it more this spring and summer. Fits exactly like you want and the material is super soft.

Very small in the bust area

I had to return this and another dress I bought. Very small in the chest/bust area

Great dress!

I gave it four stars because the built in bra does not have cups, keep this in mind if you go somewhere and you might get cold! Also, based on other reviews if you have a big chest you will get some side boobs. The material is great! I actually ordered a tank in the same material. I’m 5’2” 120 lbs and ordered a medium. The fit was perfect!

Perfect lightweight sporty dress

Love this dress! I got it for a trip to Hawaii which it will be perfect for, but I also wore it to golf as well and it was great for that too!

Odd Fit

I did love the dress material. The fit of the dress unfortunately did not work out for me. Arm holes were strange and I felt like too much of my chest on the sides were exposed.

Sizing issue

This was a great product. I returned it for sizing issue mostly. I’m 5’4”, 125 lbs, straight figure type, always a small on top 34b. This was very compressing on my upper body, just barely fit, but felt uncomfortable. I will reorder from this company in size M going forward.
